2007 Rab Summit Extreme Tent REVIEW


The Rab Summit Extreme is based on the older Outdoor Designs Summit Extreme but with a few changes. It is also the only tent in the world market constructed of the amazingly breathable eVENT fabric. Unfortunately, the current Easton 7075 aluminum poles are heavier and less strong than the previous Easton Carbon FX models. The Summit Extreme also retains the Outdoor Designs model's small footprint and low 28 inch roof, making it tight for two hikers. However, the low profile design, 13 guy-out points, and dual "donut link" tieout points make it the ultimate tent for extreme alpine placements and brutal weather conditions. This tent has few (if any) peers.

What’s Good

  • The only tent currently made of eVENT fabric - amazing breathability and condensation resistance
  • Current eVENT fabric is noticeably more breathable than the previous Exchange Lite Gore-Tex version
  • Dual sealed tie out points can anchor climbers directly to the mountain while inside the tent
  • Low ceiling, stiff poles, and 13 guy-out points create exceptional high wind stability
  • Very tough and durable
  • Aluminum Easton 7075 poles will bend rather than break like the previous Easton Carbon FX poles
  • Weighs less than 4 pounds - very lightweight for a tent that handles such extreme conditions

What’s Not So Good

  • Expensive in the U.S.- $450 but very expensive in the UK - £350
  • Very cramped quarters and a very low ceiling make it a better solo tent and passable for a pair only for the most focused summit attempts
  • A full 10 ounces heavier than the earlier Gore-Tex and Easton Carbon FX-poled Outdoor Designs version
  • Previous Easton Carbon FX poles were lighter and stronger

The Rab Summit Extreme tent is a new version of the nearly-identical Outdoor Designs Summit Extreme that we reviewed in 2005. Like the original, the Rab tent is truly focused: it is built for lightweight climbs in the most extreme alpine environments. It is extremely stable in high winds, is very breathable to keep condensation at bay (even when cooking inside the tent), weighs less than four pounds, and offers a unique system that allows you to tie off to an outside anchor without opening the tent to outside weather. While it is not the ultimate all-round tent, for alpinists pushing the envelope, the Summit Extreme may have no peer.

2007 Rab Summit Extreme Tent REVIEW - 1
The Summit Extreme from the right, rear, and left (note the 7 upper guyouts and 6 lower guyouts for a impressive total of 13).

While the footprint of the Summit Extreme is almost the same as a Black Diamond/Bibler I-Tent or an Integral Designs MK1 Lite, the 28 inch height is much lower (42 inches on the I-Tent and MK1 Lite). This difference in height also lowers the angle of the walls. This results in a tent that is difficult to sit up in and reduces usable space due to steeply-sloped walls. I spent many nights in the Summit Extreme with two people; while this is certainly reasonable for a summit attempt, it is very cramped - especially with no available vestibule. Even a solo hiker over 6 feet needs to sleep at an angle to avoid contacting the steeply-angled walls. Sleeping at an angle, though, creates plenty of room for a solo hiker and gear. Usable space can also be greatly increased by using the guyouts on the sides and back.

The benefit of this low roof, though, is the tent’s amazing wind stability. The Summit Extreme is able to spill winds due to the low height and low-angled walls, and the short poles deflect less than longer ones in high gusts. The complement of 13 guyout points (7 at the mid-tent and 6 on the ground) equate to a tent that stands up to high winds better than any two-pole wedge “bomber” tent that we’ve ever tested. With the Rab Summit Extreme (and the Outdoor Designs version before), I found myself searching for the most exposed sites to find the limits of its wind stability. Despite many nights in open mountain-top pitches in the Cascades in the middle of the winter and several nights spent on Rainier during storms, I hardly approached the limits of this tent; a ridge on K2 might be a better test (and this is the first tent I would bring to that setting).

2007 Rab Summit Extreme Tent REVIEW - 2
Snow and rain can enter the open door but a large lower flap allows for a dry entry or exit in bad conditions.

Because the doorway has such a shallow angle and there is no vestibule, rain or snow can pour in the Summit Extreme's door when it is open. To combat this, the doorway can be unzipped at the bottom and you can sneak under the large overlapping flap. During a storm, this is the only way to keep the inside of the tent dry. Despite its obvious high alpine focus, a mesh door is included to keep insects out when camping at lower elevations.

2007 Rab Summit Extreme Tent REVIEW - 3
The door is super-robust with large dual zippers for the storm and screen doors, wide seam seal taping, and large 4-inch zipper flaps with Velcro closures. Note the feet of a 6 foot climber touching the door when stretched out (left)

Another downside of the low angles and side guy-outs (when in use) is a roof that is flatter than taller wedge tents. The Summit Extreme is very strong and stands up well to snow loading, but doesn’t shed snow as well as steeper-roofed tents (but it is much better than hoop tents such as the Hilleberg Akto). Occasionally banging on the walls easily keeps the roof clear during winter storms.

2007 Rab Summit Extreme Tent REVIEW - 4
The lower angle of the roofline (due to a low 28 inch height) adds stability in winds but causes more snow to pile up during heavy snowfall.

The two biggest changes with the new Rab Summit Extreme are the poles and the tent fabric:


The former Outdoor Designs Summit Extreme came with Easton Carbon FX poles while the current Rab version comes with more-standard Easton 7075 aluminum poles. According to Easton, the 0.340-inch aluminum poles have an ultimate tensile strength (PSI) of 96,000 while the Carbon FX are 200,000 - a full 208% stronger. Both pole sets share the same aluminum ferrules though, and those have a 96,000 PSI strength, making the weak point the same. When testing the Outdoor Designs tent, I accidentally fell on it, breaking one of the aluminum ferrules but leaving the carbon shaft intact. The bottom line is that the carbon poles used in the previous version are stronger, more rigid, and lighter. I feel the switch to Easton 7075 poles is a downgrade.

Tent Fabric

While the previous tent had walls constructed of Gore-Tex, Rab switched to eVENT fabric for the new Summit Extreme. As stated in our recent article “The eVENT Single Wall Tent: Here, Then Gone - What’s Replacing It?”, this tent is the only tent in the world currently constructed in eVENT, falling into the class of “bivy shelter” due to its low height. The use of eVENT is a serious bonus for the tent - it is amazingly breathable while remaining completely waterproof. While I was impressed with the previous Gore-Tex version, I was stunned by the breathability of this tent. In the field, I only experienced minimal condensation in the form of frost inside the tent and almost zero condensation in above-freezing conditions, including wet Cascade snowstorms.

2007 Rab Summit Extreme Tent REVIEW - 5
Boiling water for over 10 minutes in the sealed Rab Summit Extreme eVENT tent left virtually no condensation…amazing!

At home, I tested the breathability by boiling water in the sealed tent for several 10-15 minute sessions. When finished, I collected condensation with a paper towel to weigh the total condensation. Each time, I was only able to detect moisture on the aluminum poles and on the seam tape - total condensation only measured 0.1 oz after a 15 minute boil. I simply could not make condensation occur in these conditions.

Given the right conditions, condensation will occur with any tent. However, I found condensaton extremely difficult to find under any conditions in the Summit Extreme. At the risk of exaggeration, I think eVENT is a magic fabric in a single wall tent, so it’s a shame it’s is only available on this one tent.

2007 Rab Summit Extreme Tent REVIEW - 6
The side and rear guyouts add a great deal of interior space in the Rab Summit Extreme. When the door is cracked open, the rear vent allows sufficient airflow to cook inside the tent.

When you need extra ventilation, such as when cooking inside the tent, open the rear vent and crack the door open at the top - the doorway will still be protected by the flap. Hanging stove systems or lanterns hang lower than normal due to the low ceiling height. Move in the tent with care when using these systems (a partner melted a synthetic jacket when brushing past a lantern).

2007 Rab Summit Extreme Tent REVIEW - 7
The dual donut system of the Rab Summit Extreme is unchanged from the Outdoor Designs version (shown). Two climbers can tie off to the mountain completely independently of the tent.

A unique feature of the Summit Extreme, shared by the older Outdoor Designs model, is the dual “donut link” sealed tie-in points. These points are created by hollow fabric loops that are sewn to the tent walls; one on top of the tent (hoop outside the tent) and one on the side (hoop inside the tent). To use these, you run a sling through the donut link on the inside of the tent and girth hitch the sling via the enclosed fabric hoop outside of the tent. Next you anchor the outside sling and tie into the inside sling. This system effectively removes the tent from the system WITHOUT having to pass a rope or runner through an opening in the tent (the entire tent could disintegrate and you’d still be safely anchored). This means that you can pitch the tent on a highly exposed ridge, on a big wall porta-ledge, or in an area of extreme wind with you and your partner secured directly to the mountain, upping security in extreme conditions dramatically. This feature makes the Summit Extreme the most secure tent on the market for really sketchy pitches.

At $450 in the U.S. and £350 in the U. K., the Rab Summit Extreme is a very expensive tent. However, it is a great value when compared with the Bibler I-tent ($540) and Integral Designs MK1L Lite ($600) and offers features such as eVENT fabric and tie-in points that those other tents don’t. The new Mountain Hardware Bunker ($450) is the only tent on the market that is made with a similar focus but it is a solo tent. For a party that needs these features and space for two climbers, the Rab Summit is an excellent value. For more casual mountaineers, however, a less narrowly-focused tent would be a better choice.

What’s Unique

The Rab Summit Extreme is a tent with a narrow focus - extreme alpine-style mountaineering - and it fills this niche without compromise. If you need the best tent with regard to low weight, wind stability, breathability, and anchoring options, this tent is your choice. You may have to accept compromises elsewhere (usable space, vestibule, expense) but if my life was on the line, this is the first tent I would choose.

Recommendations for Improvement

I would appreciate a higher ceiling on most occasions but that would compromise wind stability (and it would also eliminate Rab’s ability to use eVENT fabric). If you want a higher roof, go with another tent.

My only real gripe is the change from the stronger Easton Carbon FX poles to more-standard Easton 7075 aluminum poles. Rab may have made this change fearing that carbon poles are weaker than aluminum, but that is simply not the case; the Carbon FX poles are much stronger, more rigid, and are also lighter. In a tent this focused and expensive, the Easton Carbon FX poles are simply a better choice.

Rab bivy tent/shelter/whatever on 05/15/2007 21:27:51 MDT Print View

Having spent 4 plus days tent bound in a blizzard on Mt. Logan, once upon a time, I just don't know about such a low ceilinged shelter for situations in which there is a large risk of multi day storms moving in. I was in a Bibler I-tent w/ a climbing partner in that situation and that was an experience I don't relish repeating BUT the headroom was doable for us both and very appreciated. Granted the Rab's gotta be a helluva lot more comfy than a bivy in extreme conditions. Granted also that alpinists are expected to make it all work out in less than ideal conditions. I think this is the ticket for a fast and light approach to alpine mtneering (just get out before prolonged bad weather comes in).

Speaking of which--is this the reason that the GE powers have allowed the existence of this eVENT shelter----that it's too low to officially be considered a "tent"? I guess you came to the same conclusion, Doug. I notice that Prolite Gear lists this shelter in their bivy sack section. :-)>

What most impresses me is cooking in a sealed tent w/o condensation. Amazing. I'm kicking myself for not getting the short-lived ID eVENT TENT when I had the chance!

As to the pole downgrade, well, Rab had to save $ somewhere--keep it below that $700 pricepoint--hee, hee.

This was a very good review and I'm very happy that BPL is testing LW Alpine gear.

I would be most curious if a test that involved several competing single-wall designs using eVENT, GT, Epic, etc. would be performed that would measure both the ambient temp. and amount of air infiltration inside each tent (w/ same amount of bodies, same outside temp., wind, etc.). I'm curious about which tent (and material) traps heat best. Subjectively, Doug, how did you feel the eVENT performed in keeping in warmth and shedding wind?

You got it. The maximum height allowed for a shelter that is officially made with eVent is 70 cm, the same height as the Rab Summit Extreme. Also note that Rab always refer to it as a "shelter" never a tent.

The reviewer quoted a price of about $686!!, but I found it for $380 within 1 minute on the web; maybe cheaper if you search around.
For that amount of internal volume I think I would stick with a 2lb 10oz epic HiLight. Its epic fabric is very breathable and in my experience essentially waterproof in an alpine (sub-zero) environment.

But if you want eVENT for $380; here it is..

I have posted this before, but I will try again...
Vent Air looks like eVent, feels like eVent and quacks like eVent, because it is eVent under a different name.
So a Polaris eVent and a Polaris Vent Air will have exactly the same specs and performance.
BTW if you have not seen one in person, it looks much nicer than the usual picture you see on the Net.

I got one by offering $350 to a seller on ebay. I think if you do a search on ebay, it's the only site listing this "shelter". The Rab is way overkill for my situation, but I like tinkering with gear. I've only spent one night in it so far, foggy, rainy 50F weather, no condensation. I'm six feet tall and wouldn't want any company in there. I appreciated a small tarp above to egress while raining.

For Carbon Fiber poles: email and ask how much it would cost to make them. I had two COMPLETELY CUSTOM shock-corded poles made up at an extremely low cost. Just give them the length/width/tip type/and section length that you require. I think you'll be pleasantly surprised at the quick response and price.

More on Polaris on 05/16/2007 17:02:06 MDT Print View

The factory, production line and laminate are exactly the same as before. The change of name is purely to protect GE from any litigation. By the way this info is from someone that definitely knows what is going on, not my guess.
To me the Polaris is well up there with the Biblers , the built in vestibule eliminates the fiddle factor and makes it a smaller and lighter package than a Fitzroy with the attached vestibule, even with the fourth optional pole. I think that the 70cm height limit imposed by GE for a shelter using the name eVent will put the average Joe off and limit the sales to hard core climbers that would be less prone to burn the shelter down ( or up, if you prefer).

How about the Exped Vega ? Another clever design. I have not seen this one ,yet, but it looks a nice shelter for mixed weather, particularly when two may be stuck inside under prolonged rain periods. 34sq feet plus another 18 for the vestibules, tot weight about 70 oz.

Polaris tent is made of eVENT under another name on 05/16/2007 22:28:53 MDT Print View

Thanks to Franco for giving me the courage to mention this again here on this forum. Before the switch to Air Vent, I spoke with one of the owners of Exped about the coming change from eVENT. I was told at that time that the Polaris would continue to be made with the same fabric (eVENT) but under a different name, and my advice on naming was solicited (I don't work for Exped, just an enthusiastic friend). The Polaris is still being made with eVENT. I have one. The middle pole used to be optional but I think it is now included standard--anyway, I'd strongly recommend getting it if you intend to use the tent in heavy snow.
The Polaris has ventilation options on all four sides of the tent, plus that "magic" fabric (actually on three sides only, since the vestibule is made of silnylon: where condensation is relatively harmless, of course). Zero condensation in my limited use of the tent.

Rab Summit Extreme- additional information on 05/17/2007 00:34:33 MDT Print View

Hello everyone,

I just heard from Mary Buchmayr, the US PR person for Rab and she gave some additional information about the Rab Summit Extreme. The most important is that in the US this tent has a MUCH cheaper $450 price tag (still 350Quid in the UK). Here is the other information that she shared:

"That said, I do want to address a couple of things. First is the price.
You were correct in the UK pricing but for the US market this tent is $450.
It is available at Also, regarding the Outdoor Designs
brand: Outdoor Designs is a sister company to Rab - both subsidiaries of Equip UK. The Summit Extreme is a Rab tent but it was originally brought over under the Outdoor Designs label as Outdoor Designs was the first line to become available here.

Finally, regarding the switch from Carbon poles to Aluminum poles, this was largely due to supply and quality issues. While the Carbon poles may have been stronger, they were not unbreakable and a break in one of the Carbon poles would be a critical failure as it couldn't be repaired in the field.
This was a primary consideration in changing this feature of the tent. As you said in your review, this tent was built for the most extreme alpine environments, so it is to those users that the decision was made to ensure that the tent was field reparable in as many instances as possible."

Thanks for the additional information Mary!

Hi Doug - thanks for the update

I bought a Summit Extreme a few months ago but haven't had the chance to use it yet. As I am based in the UK it would be interesting to get an explanation from Rab over their pricing policy. Why is it that their own home grown customers have a much heftier RRP? (and they're not the only UK company doing this, for example US customers get the INOV8s at a much lower RRP than UK customers)

Judging from the photos of Doug in the BPL review (he is a little over 6'), the tent is higher than 70 cm and probably is the 89 cm (35") measured by Franco. However, that is still one short tent for a 6 footer and I would reserve this tent as a final summit assault style shelter (if I had this). This might work for some of you wee folk.:-)>

Hello all,

I stand corrected. I just measured the tent again and the correct interior height is 85.5 cm or 33.7 inches.

Rab Summit Extreme on 07/15/2007 02:57:57 MDT Print View

Let me make my position clear.
1) It is entirely possible that my measuring tape was at an angle, hence the 1" difference in the measurement. My point was to prove that it is not 70 cm in height.
( I asked the only other customer in the area to take the picture, the staff were not aware of what I was doing)
2) I very much enjoyed the professional review by Doug and have no problem with it apart from the
point in question
3) After searching the net for info on this shelter, I found that every single outlet had the same erroneous specs.
4) The shop where the tent was on display often has different tent specs on their brochures and Point Of Sale material from the ones published by the manufacturers. In fact this prompted me a few years ago to challenge one of the local brands and all I got from them was BS. Eventually the official specs were amended but are still not accurate. ( and yes, I averaged several tents to come to my "acceptable" weight). In the case of the Summit they (strangely enough) had the same wrong specs as everybody else.
5) I have no interest in this tent personally, however I think that it is a better version of the Bibler and ID of similar design. ( I am not a climber,nor a masochist) If I needed to carry a shelter on an "Everest" type expedition solo , this would be it.

I just want to comment on this comment:

"Unfortunately, the current Easton 7075 aluminum poles are heavier and less strong than the previous Easton Carbon FX models."

Easton Carbon FX tent poles are as strong as our .340 7075 T9 (96,000 psi) and in fact are designed to have the exact deflection of the .340 7075 T9 (.070 at 18"). The Carbon FX is designed around the .340 and a tent design can be created as a hybrid with aluminum and carbon sections. Also, the Carbon FX is lighter than the 7075 T9 .340, but it is 3x the price of aluminum. The weight difference is 5.543 gpi (grains per inch).

It would be awesome if you could post the component weight of the tent. How much did the poles, body, guylines, and the stakes weigh each?

No love?

Does anyone out there own this tent, who could let me know how much the body alone weighs and how much the poles alone weigh?

Did anyone ever help you out with the weights of the Rab? If not, I have the tent and could weight it for you.

I would love weights. This tent is on my short list if a couple mountain trips fall into place.

NEMO Tenshi fabric on 11/20/2007 14:06:17 MST Print View

The NEMO Tenshi fabric is called OSMO. It has a 30D polyester ripstop base with a proprietary monolithic laminate on one side.

We (I'm an engineer at NEMO) changed over from eVENT for a few primary reasons:

1. the eVENT fabric being used was not fire-retardant and for tent to be available everywhere without exception, all fabrics must be FR-treated

2. The NEMO OSMO fabric (5618 g/24hr/m2)tested better in our independent lab fabric tests than eVent ev5005 (5304 g/24hr/m2). The test we use is ASTM E 96 METHOD BW (inverted).

3. The NEMO OSMO fabric has a lower weight (2.22 oz/yd2) than the eVent (2.84 oz/yd2).

Hi Connie,
thanks for stopping by.
A small question: I've read somewhere that the Osmo fabric is a formulation of Toray Dermizax. Could you confirm or deny this?

Hi Tom,

The NEMO OSMO fabric is a propietary fabric made by a company called Formosa -- so, it is NOT a Toray fabric.

Let me know if I can answer any more questions.

If BPL still believes that eVent is still the ultimate material for tents, then the Polaris is a top contender for the title of ultimate single-wall tent, right? Or do the new fabrics (OSMO perhaps, and others) offer similar performance in the Rockies? Might you treat us to a review?

2007 Rab Summit Extreme Tent Review on 08/16/2010 18:46:30 MDT Print View

According to the reviewer, the Rab Superlite tent/bivy has a mesh front door for camping in the lower elevations. I looked at a Rab Superlite today and I saw no mesh door. Have the folks at Rab removed the mesh door on this tent/bivy since it was reviewed in 2007? Thanks

Gabriel. This was a review of the Summit Extreme, not the Summit Superlite. I don't think Rab make the Summit Extreme anymore.

2007 Rab Summit Extreme Tent REVIEW on 08/18/2010 06:35:38 MDT Print View

Mike you're right... I go this from Rab early this morning:

Hi Gabe,

I think I figured it out. the article you mentioned is reviewing the Summit Extreme, not the Summit Superlite. What this boils down to is: You were correct in your original statement of the Summit Superlite having changed since the review to remove the mesh door.

When the Summit Extreme was reviewed by, it had the mesh door. Once it had been updated (in 2009) to make it lighter (by 2 oz) the name was changed to its current name of Summit Superlite. The current model does not have a mesh door.

Is the removal of the mesh door the only change?
In my view this is a retrograde step.
The mesh door allowed some other options, like leaving the door open near lakes riddled with sandflies etc.
I also note references to this being three season.
Is is a 3 or 4?
