ULA Circuit with cuben hydrid fabric. on 11/14/2012 15:17:40 MST Print View

Just had this backpack shipped by the fine gentlemen at ULA and I'm pretty damn excited. The pack body fabric is the same Zpacks uses for their Exo backpack—1.43 oz/sqyd cuben fiber with a protective layer of 50D polyester on the outside. This is lighter than the fabric used in HMG backpacks, but not by much (2.92 oz/sqyd vs 3.3 oz/sqyd). I'm planning to tape the inner seams with cuben tape to complete the rainproofing.

@Kevin: it's 4.5 ounces lighter than a typical Circuit. In size large, it's 36oz with every option. I'll be removing everything except the aluminum stay and one water bottle shoulder strap, so it should be right around two pounds.

@Jason: Custom. I also had them add a second side compression strap because I'll be carrying Altai Hok skis on the pack through the winter.

Did anyone else initially think the pack has a bit of the Holy Glow like something you witness for the first time and can't help but hearing a church choir in the background going "ooooooOOOOOOOOHHHHHHH!!!"? I honestly thought it was photoshopped for a whole second to reinforce the cuben fiber arc of the covenant angle, for a whole second. Made me laugh.

Well, I got it and it's a beautiful beast. I ordered some 1" cuben tape from Zpacks to tape the interior seams. It's never going to be as waterproof as an HMG bag just by virtue of the features and how it's constructed, but it'll be waterproof enough to eliminate a pack cover here in Oregon.

White Cuben Fabric on 11/30/2012 15:42:32 MST Print View

That is one sweet lookin pack. I want to get one but I'm concerned about the white color used on these. I can't imagine that stays white very long.

Anyone have experience with these White cuben bags from Zpacks, Hyperlight Mountain Gear, etc....Does the white fade over time to tan, brown...?

Can't find any pics from a somewhat worn bag in this material.

For me, load lifters wouldn't make up for the 10 oz weight differential. I would want something lighter than 36 oz that was cuben otherwise what is the benefit?

Re: Re: Re: Re: Cuben Hybrid Circuit on 12/02/2012 18:26:10 MST Print View

The bag is 34oz with the features I don't use removed. That's less than 6 ounces heavier than a Windrider. I say it has a better frame because of the hip belt, the carbon hoop and stay, and the load lifters. At the minimum, everyone would agree load lifters are better than not at the loads these packs are designed for.

Edit: not to mention the torso length adjustment of plus or minus 1.5 inches that ULA packs afford.

The hip belt on the Windrider is 4" wide and just as long ( padded portion) as the Circuit. The Large belt is longer than the Medium, etc. you can have HMG swap out a larger or smaller size for you.

Not adjustable torso; just 4 different torso sizes.

Nice looking pack, Kyle.

Your side profile picture with the pack on is one of the very few I've seen where the Circuit looks like it's actually fitted and riding correctly. Most of the photos online, and what I've seen on the trail, the pack appears to be slumped below the user's shoulders with the load "lifter" straps angled straight across or even downward from the shoulders. This is actually what has put me off of trying one.

Have you had a chance to put some miles on it yet?

It's been out on two overnight snow camping trips so far—only about 15 trail miles all told. That said, I was carrying quite a bit more weight than I typically do and it carried really well.

Here's a photo I took of myself on the first trip with about 30 pounds on my back. It's hard to see but the load lifters are still being used properly:

thanks, Kyle on 02/20/2013 15:48:52 MST Print View

Thanks for the feedback. The pack looks good and more importantly, it looks like you're having a good time.

One more question if you don't mind: how do you like the hipbelt? Specifically, it looks pretty dang wide. Much wider than any other hipbelt I've ever used, including traditional non-lightweight packs (e.g. Osprey Aether). Does it cause any binding or restriction of movement like high leg lifts while scrambling?

Everything about the Circuit seems great, but I'd really like to try one on before I buy, which is why I have so many questions. I may just have to accept the return shipping costs and order one to try it out.

Thanks again.

Wide belt on 02/20/2013 15:54:31 MST Print View

Using the same belt on the Ohm and Catalyst, I find it to be very comfortable. Definitely not restrictive or binding. The best thing about it is that the buckle has straps leading to both the bottom and top of the belt. This seems to make the belt cradle the hip bones comfortably and securely. Best hipbelt I've used in 40 years of backpacking!

ULA usually charges a $50 fee for custom work, and then whatever the fabric up charge is. Going from Robic 210/Sil to all Cuben hybrid is $50 for example.

"Going from Robic 210/Sil to all Cuben hybrid is $50 for example."
It's $80 these days.

I imagine simply replacing the (70D?) upper nylon bit with Robic would be much less however.

ULA Catalyst Cuben Hybrid on 03/15/2013 20:39:20 MDT Print View

I got my cuben hybrid Catalyst from ULA this week. It's sort of a pale grey/green/blue cuben hybrid. It's actually dark green cuben inside and sorta white polyester on the outside. It takes away the brightness of the pure white cuben hybrid which is all I wanted. Aside from the fabric, it's got extra straps on the bottom and no hydration ports (to decrease water influx during packrafting).

Catalyst 1

The bottoms of the side pockets are cordura. The rest of the pocket is 210D ripstop nylon and then the body is 1.5oz cuben + wov.32 polyester hybrid (3.3oz). Same stuff as HMG.
Catalyst II

ULA made all the little accents the same cuben hybrid fabric for a cohesive look. Great attention to detail as with all ULA packs.
Catalyst III

For better scale, here's a 2400 HMG Windrider and a ULA Ohm (1.0). It's a nice size step up from my Ohm - large without being enormous.
Catalyst IV

As an aside, Roman Dial's "packraft fold" is easily the best way to pack a raft. There are some nuances to it though, so watch Roman's video and PM me if you're having trouble making it work. Here's a rolled raft in the Alpacka sack (which is hard to get it into) versus the packraft fold which is much more easily accomplished:
Packraft fold

Here's two folded packrafts, easily stored side by side in the pack:

And the obligatory picture of me wearing the pack. I don't look as thrilled as Kyle, but he got outside with his. I'm slaving away at university for another 4 weeks. The pack is pretty much right on 40oz right now with maybe 1oz of strap trimming in its future. The pack fits well and should be great for its intended use (+7 day hiking trips or packrafting trips)

Circuit vs ohm...I want more cuben gear!!!! on 03/15/2013 21:15:05 MDT Print View

Chris at ULA said he thought the ohm would likely be too small for a JMT (and hopefully?!!) a PCT thru if I carried a bearikade weekender. Dan, looking at all those packs side by side makes me a) sooooo want one of them and b) think the circuit is an awful lot of pack.

My non-bear canister 3 season base weight is 9 pounds.

Would I be unhappy trying to carry an ohm with a canister and possibly 8 days of food/fuel?

Ohm on 03/15/2013 21:23:01 MDT Print View

You're probably aware, but just to be clear my new pack shown above is a Catalyst - one size larger than Mike's Circuit. So imagine the Circuit fitting between the the Ohm and Catalyst in my lineup picture. I think it's about the same height but narrower.

I've carried an Ohm and a bear canister on a few occasions. The longest was 4 days, but I had most of the food for two so it was close to an 8 day supply (no it didn't all fit in the canister, does it ever?). The trouble with an Ohm and a bear canister is that most (all?) bear canisters have that ridge in the middle. The ohm has a thin back pack (1/4"?) so this ridge pokes/rubs on your back and there's really no way to pack it so it doesn't.

I personally don't think the Ohm is that bad at 35 lbs - and that's the regular Ohm, not the cushier Ohm 2.0. So the weight of 8 days of food and a bear canister can work if you've got a high-ish discomfort tolerance and it's not a long term situation. Almost regardless of packweight, I find the ridge on the canisters to be more of an issue. I usually get a little spot rubbed red on my back from it, so I pack the pack differently each day so it rubs in different spots. So for occasional bear canister use the Ohm is fine, but if you're using a canister regularly then I'd look at getting a canister without a ridge (if they exist) or getting a different pack.

Jennifer, you could always look at the HMG Windrider 3400, which has the beefier shoulder straps and belt from the Porter. It will be more than big enough. You can put your food inside your pack while hiking and strap the bear canister to the top "Y" strap, empty of course. At camp, put the food in the canister.

Dan, that looks really nice. Nothing against Kyle's pack, but seeing ULA do all the detailing with the hybrid material makes a big difference aesthetically.

I'm really interested to see where they go developing there packs with this material--especially as they move beyond just doing their current models to really take advantage of some of the differences in the fabric properties.

It looks like they may be giving HMG a run for their money. This is what I like to see--two fantastic companies spurring innovation in each other.

So I really need to just stop whining and go buy some packs (thanks Dave for adding yet ANOTHER one to consider!) early and start trying to carry my bear canister unnecessarily on my weekend trips to see what I think.

I was so set on a Circuit until the new Exped Lightning backpacks hit the market and now I'm stuck. I was going to grab a 45 liter Exped Lighting from Campsaver.com for $160, but missed the boat. I thought it was a reasonable price and they have a great return policy so trying it out would be painless. Well, I missed that and I'm just going to give up this season and carry my boat anchor, Cilogear 45L Worksack @ 3.5 lbs.
