Gossamer Gear Gorilla Backpack Review - 1
The new Gorilla backpack is Gossamer Gear's latest and greatest - 2800 cubic inches and 24.5 ounces (size Large). It's constructed of durable fabrics and mesh and has a new contoured removable aluminum frame.


I still have my original Gossamer Gear G4 frameless backpack. It has a few holes in the bottom from scraping over rocks, but it's still a perfectly good pack. Fast forward to the new Gossamer Gorilla pack, and you will notice some familiar features - front and side mesh pockets, rolltop closure, wide shoulder straps, sleeping pad sleeve, and you can still stuff socks for padding in the shoulder straps and hipbelt if you want. Conceptually, Gossamer Gear packs have not changed, but there are huge improvements in the details that make them a whole lot better. The new Gorilla backpack, with its durable fabrics and removable curved aluminum frame, is state-of-the-art Gossamer Gear. (And you can still purchase a new G4 if you need a replacement.)

Gossamer Gear introduced an ultralight removable frame in their Mariposa backpack back in 2004, consisting of two straight carbon fiber stays (0.9 ounce/pair) inserted into sleeves on the backpanel. The Mariposa could be used either as a frameless backpack or with the stays inserted to increase its load carrying capacity. The concept was a big advancement at the time (an ultralight frameless or internal frame backpack ALL IN ONE!), but the straight stays were less than ideal for pack fit and load-carrying comfort. After experimenting with several prototypes, they developed a curved aluminum stay (3.4 ounces) that fits into the same sleeves on the backpanel. I have tested both versions and can unequivocally say that the curved stay, along with other improvements incorporated into the Gorilla pack, are a big improvement. This pack is near perfection!


The new Gossamer Gear Gorilla is designed to be as versatile as possible. The pack comes in three sizes (S, M, L) and three hipbelt sizes are available. The pack body is the same for all pack sizes; the shoulder straps are simply sewn on at different heights to create different pack torso lengths. Many components (frame, hipbelt, sternum strap, shoulder strap and hipbelt padding, bungie system) of the pack are removable, so the user can choose the components he/she wants to use. Accessory hipbelt pockets are available for hikers who want to add them.

The Gorilla (2800 cubic inches, 23.2 ounces size Medium) is the second lightest internal frame backpack available. The lightest is the Gossamer Gear Mariposa Plus (3600 cubic inches, 22.3 ounces size Medium), which is constructed of lighter fabrics and has the same stay (yes, the stay is interchangeable, and older Mariposas can be easily retrofitted).

The key factors that differentiate the Gorilla (besides its lower volume) are more durable fabrics (210 denier PU coated ripstop body and durable stretch nylon pockets) and removable curved stay. The revised Miniposa (14.5 ounces size Medium) has the same dimensions and feature set, but it is constructed of silnylon and does not have a stay. The difference in weight between the two packs is 7.8 ounces, which is the weight added to the Gorilla by the removable frame and durable fabrics.

There are six loops in the side seams to attach a bungie system (not shown). The backpanel view (top right) shows the pack's wide shoulder straps and backpanel sleeve to hold a sleeping pad. The hipbelt pocket on the left is my camera case, and the right pocket is a Gossamer Gear add-on hipbelt pocket ($15). A side view (bottom left) shows a lower mesh pocket designed to make water bottles reachable. And the top view (bottom right) shows the pack's drawcord closure and top compression strap.

Like other Gossamer Gear packs, the Gorilla has a mesh sleeve on the backpanel (left) that allows the user to insert a sleeping pad for padding. The mesh used in the sleeve is much improved over previous versions. Shoulder straps (center) measure nearly four inches wide from edge to edge, have removable closed cell foam padding, and are faced with 3D wicking mesh on the inside. The removable hipbelt (right, 4.1 ounces size Medium) is a similar width and construction.

The new stretch nylon pockets on the Gorilla are really stretchy and very durable. The bottoms of the three exterior pockets (one front, two side) are 210 denier ripstop nylon for increased durability.

Note that the Gorilla pack does not have a torso length adjustment, so it's important to measure your torso length and choose the correct pack size. Hipbelt sizes are based on hiker girth. The only pack fit adjustment on the Gorilla is the shoulder strap length; the pack does not have load lifter straps or hipbelt stabilizer straps.

Field Testing

I tested the Gorilla on a number of on-trail and off-trail summer backpacking trips in the southern Rockies, carrying weights ranging from 10 to 25 pounds. For one quick overnight trip, I stripped the Gorilla down to a 15.6 ounce minimalist frameless backpack (I did leave the 0.4 ounce shoulder strap pads in) and carried 12.5 pounds. I also tested the pack fully equipped on walks near home with weights ranging from 25 to 35 pounds to determine its comfortable weight carrying capacity.

Gossamer Gear Gorilla Backpack Review - 6
Fully loaded Gorilla pack with 21 pounds (left), and the same pack used on a day trip from a base camp (right).

My immediate (and continuing) impressions of the Gorilla are as follows:

  • For me, the pack volume is perfect for ultralight backpacking (same for the Miniposa). It has the right amount of room for my ultralight gear kit, plus room for food, water, and fuel for up to eight days.
  • The construction is excellent. Stitching is close and tight, and there are adequate reinforcements in stress areas.
  • The new curved aluminum stay is golden! I really like the pack's fit.
  • I love the pack's wide shoulder straps for distributing weight, and the 3D mesh backing resists sliding on my shoulders.
  • The new stretch nylon exterior pockets really stretch out and will hold a lot of gear, and they're very durable. Outside pockets on some packs are tight and hard to get items in and out, but not so on the Gorilla.
  • The backpanel sleeping pad sleeve is much improved; it has stretch nylon panels on the side and 3D wicking fabric face, and it doesn't stretch out of shape and bleed dye like the mesh used on the old Miniposa.
  • The side pockets are shorter and angled to make a water bottle reachable with the pack on, but I use a hydration system, so I would prefer taller side pockets that would hold more (can't satisfy everyone!).
  • It's easy to access the hydration sleeve, and it's very easy to pass a drink tube through a port and down a shoulder strap.
  • The Gorilla functions well as a daypack for going on a day hike from a base camp
  • I really like the durable fabrics; this pack is built to last. The added weight is about 4.3 ounces.
  • The hipbelt requires some effort to remove because it has a Velcro patch on both sides. It's much easier to put back on.
  • Likewise, the sternum requires some effort to remove and replace. A screw driver helps.
  • The stay is very easy to remove and replace. The curvature can be changed by bending it over something round, but I found the pre-bent curvature just fine.

The heavier loads I carried with the Gorilla were 21 pounds on a base camping trip with my wife, and 25 pounds on another trip where I carried a friend's ridiculous 7-pound tent to help reduce his 40-pound-plus load (we talked a lot about how to reduce his pack weight!). I found the Gorilla, with all of its components, surprisingly comfortable carrying these weights. The wide shoulder straps really function well to distribute weight, so I did not have any shoulder strap pain at all, and tightening the hipbelt worked as expected to transfer weight to my hips.

From my weighted pack tests I conclude that the maximum weight carrying capacity (for me) for the Gorilla is about 30 pounds, and the comfortable weight carrying capacity is around 25 pounds. The stay in the Gorilla pack simply resides in sleeves on the backpanel. It is not anchored to the hipbelt at all, so there is no structural connection to support the weight. My opinion is that 25 pounds is a comfortable maximum weight for this pack, but it can easily carry up to 30 pounds when needed.

The Gorilla can be stripped down to a frameless backpack weighing 15.6 ounces (with 0.4 ounce shoulder strap padding left in). It requires some effort to remove the hipbelt and sternum strap, but once it's accomplished, pack weight can be reduced by half a pound. The Gorilla is delightful to carry frameless with a light load; the wide shoulder straps distribute weight very well, and the 3D mesh backing minimizes sliding on the shoulders.


The following table compares packs currently available that have removable stays, allowing the pack to be used either frameless or with an internal frame. Note: information is manufacturer data for a size Medium pack.

Pack Total Weight With Stays Volume (cubic inches) Fabric Stay Description Stay Weight (ounces) Adjustable Torso Cost (US$)
Gossamer Gear Gorilla 23.2 2800 210d ripstop Contoured aluminum tubing 3.4 No 165
Gossamer Gear Mariposa Plus 22.3 3600 70d ripstop Contoured aluminum tubing 3.4 No 160
Six Moon Designs Starlite 30.0 4200 210d Dyneema 2 flat curved aluminum 5.0 Yes 175
Six Moon Designs Traveler 31.0 3800 210d Dyneema 2 flat curved aluminum 5.0 Yes 190

Note that all comparable backpacks have a much larger volume than the Gorilla, so the Gorilla is in a class by itself. If you are looking for a smaller volume backpack with removable stays, the Gorilla is the only one available. If you need more volume for lightweight backpacking or bulkier loads, you have a choice of three pack models that have removable stays. Of those, the Gossamer Gear Mariposa Plus is the lightest by 8 ounces, but it does not have an adjustable torso.


Some readers may wonder why a 2800 cubic inch backpack needs a frame at all. The general rule of thumb is that a frameless backpack is comfortable to carry with loads less than 20 pounds. Of course that number will vary a bit up or down depending on hiker size and strength. For carrying more than 20 pounds, an internal frame backpack is recommended, and the sturdiness (and weight) of the pack will increase as the load increases. The Gossamer Gear Gorilla pack is extremely versatile because it can be used as a frameless backpack up to about 20 pounds, and the lightweight stay can be added to comfortably carry loads up to 25 pounds, or more. With food, water, and fuel, my pack weight is usually in the 17- to 21-pound range, occasionally higher for longer trips, so I find the frame to be a benefit on most of my trips.

Another potential issue may be the need for heavier, more durable fabrics in an ultralight backpack. There are definitely lighter packs available for ultralight backpacking, but they are strictly frameless backpacks. A removable frame backpack requires stronger fabrics to avoid damage from the stays wearing through or seams blowing out when the pack is under stress from heavier loads.

More durable fabrics also extend the life of the backpack considerably. The initial trend in ultralight frameless backpacks was to make them as light as possible, which meant really light fabrics like spinnaker and cuben fiber. And, yes, it is nice to have a super light pack for the times you want to backpack as light as possible. However, the current trend is to balance lightweight and durability, as evidenced by many of the current backpack models offered by Gossamer Gear, Six Moon Designs, Ultralight Adventure Equipment, and Mountain Laurel Designs. Pack designers and users have realized that incorporating durable fabrics into a pack does not increase weight that much, but it vastly increases durability and longevity. If you subscribe to that rationale, the Gossamer Gear Gorilla pack is an excellent choice.

Since I most frequently carry loads in the 17- to 21-pound range, I was inclined to use the Gorilla with all of its components because they simply work well together to provide a very comfortable pack that carries a moderate load very well. I personally found all of the features on the Gorilla worth their weight, except the bungie system, which I don't find very useful, but it's easily added when it's needed. The 1.6-ounce SitLight pad provided with the pack is also very useful as a backpanel pad, if you don't use a sleeping pad that is compatible with the pad sleeve (like the Big Agnes Clearview pad or Therm-a-Rest NeoAir pad). The bottom line is the Gorilla comes with a full complement of features, and most of them are removable, so you can set up the pack to match the trip and your personal preferences to your heart's content. Or, if you simply use the pack the way it comes out of the box, it's still very light and very comfortable to carry with moderate loads.

  • Many components are removable, allowing the user to set up the pack for individual trips or personal preference.
  • Durable fabrics and mesh.
  • Contoured tubular frame is very lightweight and fits well.
  • Stretch nylon pockets are very durable and stretch easily to hold a lot of gear.

Great article and well written. Though I am not compelled to go out and buy this pack. Maybe because the author is slanted as he uses a G4 already (not trying to offend)?

I would like to see this pack compared to some of the other new packs on the market. Maybe the BPL staff could have a contest and everyone could take a turn with a different pack. Decide the over all favorite and give us pros and cons.

Has anyone looked at the new light Osprey packs? I was suprised by the well thought out features of those. Heavier than anything I have anymore. But I like them. They are on clearance at REI.

Love my Gorilla too on 10/13/2009 16:41:48 MDT Print View

I've used my Gorilla with loads up to 26lbs and it carry's like a dream. I have it outfitted with dual shoulder strap and hip-belt pockets. I'd did have the hip-belt pockets coming loose from where they anchor with the Velcro tabs, but I plan to put a few stitches in, attaching the tabs to the hip-belt to alleviate this problem.

Re: Love my Gorilla too on 10/13/2009 20:17:59 MDT Print View

+1 Gorilla so far. I have used it for less than 200 miles... but so far it looks like it's going to retire my GGVT which has been my goto pack for the last six years. I pretty much agree with everything Will said.

The one thing I would add is that the stays aren't connected directly into the hip belt which can limit weight transfer. If a bit of care is taken when packing this isn't an issue though the pack has a bit of side-to-side motion around the center where the pack fabric and he belt connect. I actually find this slight pivot makes the pack more comfortable for me with <25lb loads.

As to the Osprey Exos line... there was a review of the Exos also by Will here earlier. For my purposes I found the Gorilla just the right size where the Exos 46 was the wrong shape to take a bear canister and the 58 was too big. For me, the Gorilla is more comfortable carrying up to 25lbs. I thing that from a feature standpoint they are most pretty nice. The only thing that the Exos is notably better at is back ventilation. The Gorilla is worse than average, the Exos is better than average.

Nope. Those were the two packs I tried this summer. I tried the Ohm the first half of summer and then switched to the Gorilla. I think the Ohm is visually more attractive, likely more durable... and I might have slightly preferred the Ohm's usability (type/location of pockets, closure system, etc). But when it came to carry comfort I much preferred the the Gorilla. I think the combination of the shaped stays and the encircling hip belt of the Gorilla are an improve over the the wing attached hipbelt and strait stays on the Ohm. The Ohm carry reminded me of the GVP Miniposa with the strait stays. Ok, but not great.

An annoying feature of packs like this, is that the sleeping pad can become soaked when it rains. More an annoyance than a major problem, but enough to put me off. My Starlite suffers from the same issue.

I was very close to getting a Gorilla, but in the end I felt the capacity was a bit too small to make the most of its weight carrying ability. Instead I decided to try the frame less route with an MLD Exodus. For a few years now I have been using a frameless sack I made myself by modifying an existing sack and have been quite pleased. However if the Exodus doesn't work out for me I will going back to the GGG.

Deadbear here!! Just finished the 130 mile 100 mile wilderness... Monson to Katadhin... 6 pound base and 8 pounds food and water, HOOOOOORRRRAAYYYYYY for the gorilla!! A very cold and mostly wet hike the Gorilla responded superbly.. Even working as a foot box cover to protect my down on the worst of nights... Large shoulder straps no problem for me although you need lots of poofy down , or a bear canister, to fill it up to the point you can tighten down the center strap... The pockets are perfect.... did i say perfect? I mean absofreakinglutley perfect... Wet tarp, water bottle, rain jacket, camp shoes, any thing you can imagine... Greatest pack ever!!!

Quick edit- After reading the rest of the posts I just wanted to say that 5 days/ nights of intermediate to heavy rain/ snow on white top/ ice on Katadin, my gorilla happily kept everything dry without rain cover... The only stuff that got wet was because of me being s moron!!!

Thanks Grant for your help and absolute amazing customer service!!!!!

Stay Correction on 10/14/2009 07:30:37 MDT Print View

I believe the statement that the stay is made from aluminum tubing is incorrect. The stay in my Mariposa Plus is made from solid aluminum. I had a discussion with Grant at GG about it. He said they tried aluminum tubing but ran into manufacturing and durability problems. The discussion was for the Mariposa, but since they list the same stay weight (3.4 oz.) for both packs, I assume the same rod material in the Gorilla.

I wouldn't characterize this as nitpicking because in a backpacking genre in which label removal as a means of weight reduction is considered rational, so too then would a quest for a workable means of forming high strength tubing to shave of a few ounces.

I would also like to add another facet to this review. The company behind the gear is almost as important as the gear itself, and in this respect, I find Gossamer Gear in the very top tier of the industry. They are responsive to inquiries and stand staunchly behind their products. They go to great lengths to assure long term customer satisfaction.

Ohm on 10/14/2009 07:36:40 MDT Print View

My Ohm in medium with no accessories weighs 20.1 ounces so the statement about the Gorilla being the 2nd lightest internal frame pack available is incorrect. At 3000 cubes it's also a direct competitor with the Gorilla as mentioned above.

Thanks, Will. Some questions:

1. Are you saying that the NeoAir can, or cannot, be used in the pad sleeve? Would the NeoAir size matter (I have a Large), and would you have any NeoAir durability concerns when doing so?

2. What size of bear canister is usable with this pack? I have both the BV450 and the BV500; will they both work?

> How would you compare the volume of the main body of the Gorilla?

I would say that it is less. The Gorilla lists the main bag and collar to be 2400ci. The GGVT main section (without the ridiculous collar) is somewhere between 2600-2800ci. The packs are similar width, the GGVT main body is a tiny bit taller, and the real difference is that GGVT is deeper.
