Frequently Asked Questions

Will a Bear Canister fit inside a Mariposa? Yes, all models of bear canisters will fit vertically in this pack! Smaller designs like the Bare Boxer and the Bear Vault 450 will fit horizontally in the main compartment.

How do I attach trekking poles or an ice axe to the backpack? We suggest using our Pole Storage Bungee and then running that through one of the many attachment loops provided on the packs exterior. This will insure secure storage.

My First Lightweight Backpack!Review by Alyx
I just returned from a 3-day ladies-only backpacking trip with the Mariposa 60, and though I'm just starting to dive into the ultralight world, I'm a convert for life! At 6 feet tall and 145 lbs., the medium pack and waist belt fit perfectly. I cut about 10 pounds compared to my last trip with another pack. With food and water, it weighed about 26 pounds. The outer pockets offer convenient access for snacks and small gear. The hip pockets are spacious enough to fit sunscreen, lipbalm and other essentials. My tent fit nicely in the larger side pocket. The foam pad on the backside of the pack can be removed and used as a pillow or sitting cushion. Some of the ladies in my group removed the foam before the trip, but I appreciated the extra comfort. Overall, I'm very happy with this pack! (Posted on 9/17/15)
Perfect pack for this woman!Review by Bluebird
I just took my Mariposa 60 out for its first 3-day trip on the Foothills Trail. I can't say enough good things about this pack. I have owned the original Mariposa for years and it never disappointed but this new pack is amazing!

Before going into details I have to admit that I used a different hipbelt. I fell in love with the Elemental Horizons Hip Belt with a four point adjustment system that was too comfy to pass up so I married it to the Mariposa and it was the perfect pair. The owner of EH custom made the belt for me to match the Velcro of the Mariposa (and removed the support straps...didn't need them).

I am a 5'6 woman with a 18" torso 30.5" hip. My pack is a M and the hipbelt that I ordered the pack with was a S. It was too small (cushion didn't wrap all the way around my hip bones) so I sent it back. Hence the EH belt instead. The M GG hip belt would have been fine I am sure.

First off, my total weight with food and a full 3L platypus was 21 lbs. The pack rode comfortably without any wobble, rubbing or shift.

Here is how I packed it:
Main compartment: sleeping bag, tent, clothes bag, cup, sleeping pad (rolled and fit in cup), and food. 3L Platy in sleeve with hose coming out of port. It was hard but not impossible to get my hose through the port because I use a bite valve cover. BTW...the thumb loop is a great spot to hold your valve...I had it run down the shoulder strap and then "Ued" it up to fit inside the loop. Very convenient. I had plenty of room in the main for the times I need winter wear.

Long Side Pocket: Tyvek ground sheet, tent poles and stakes. I used the extra cord and cincher that comes with the pack to cinch it down.

Main Pocket: raincoat, visor and small pack towel (used it for wet fly on the last day due to dew.)

Small Bottom Side Pocket: ditty bag with first aid, personal and extra stuff

Small Top Side Pocket: trash compactor bag for rain.

Top Lid: book, phone, cards and cash

Hip belt pocket (with EH hip belt): energy bar, lip balm, map

The pack held up awesomely. Although I don't sling my pack around, I didn't have any problems with fabric rips. The Sit Light Pad was easy to get in and out, served me well at lunch and dinner, and was super comfortable on my back. My hiking buddy was impressed and kept commenting on how compact the whole pack looked and was thinking about the Mariposa for her next pack as well.

You will not go wrong with this pack! Gossamer Gear did it right and I would put this up against any other lightweight backpack on the market. (Posted on 9/17/15)
A+ performance in the high countryReview by Steve
Just back from my first extended trip. Half the trip was above treeline, off-trail scrambling including plenty of loose rock fields.
Pack fit like a glove and was very comfortable - I was carrying some extra gear for my son and a lot of food - trail weight was generally 33-36lbs. A lot more than I would like to carry, but this pack made it feel like less, and the solid fit when traversing rock slides was a difference-maker.
Without question, best pack I have ever owned.
If only carrying 20-25lbs, I might leave home the AL stay and save a few more ounces, but I was glad to have it given the load I was carrying.
I got the large with a medium belt; I am 6' & 170# with a 32-33" waist, 41" chest. Slightly longer than average torso for my height...hope that helps someone sizing their Mariposa.
The only thing I would have changed would be having the hip belt pockets (which are really quite small) be slightly extra 25% would be perfect.
Cheers. (Posted on 9/5/15)
Great pack!Review by Porrick
Dragged my Mariposa Plus through many multi-day workup hikes in MD, VA, and WV and then out to Philmont Scout Reservation in New Mexico with my son's troop for 90+ mile trek. The pack easily swallowed my minimal base gear, 4 liters of water, and 6-8 meals of ridiculously heavy Philmont-issued food with room to spare. I really like the external pockets -- especially the long one for my tent. The pack held up beautifully and kept my post-rotator cuff surgery shoulder happy for 13 days in the backcountry. Very, very happy with this pack and am looking at a Gorilla 40 for shorter (and lighter) trips. Thanks GG!! (Posted on 8/21/15)
The pack that can handle miles of talus!Review by Princess of Darkness
I recently hiked the Sierra High Route along with a few other friends and I was the only one carrying the Mariposa (everyone else had the Gorilla or the Kumo). The Mariposa seemed to carry the bear can better as well as my bulkier load (I carry more clothes than others). The pack also did QUITE well on the granite talus, most other folks ended the trip with a lot of pack abrasion and a few holes in some cases.

Although the Mariposa is bigger, it was definitely a winner for such rugged terrain and oh so comfortable!!! (Posted on 7/26/15)
Great Pack for Gear Intensive TripsReview by Anish
I use a Mariposa for my glacier climbs and extended technical trips. It easily accommodates large quantities of/high volume gear. My most recent trip with it was summiting Mount Rainier where it worked perfectly. (Posted on 7/22/15)
Great First Lightweight Pack!Review by John
I was a little nervous about ditching my bigger (heavier) name-brand pack for this one, mostly because of the recommended weight limit. I've never been able to pack that light! But I forced myself to get used to it.
I took the Mariposa out on a few overnighters to get a feel for it and experiment with all worked well! It held everything I needed and organization was easy.
Then I took it out for three weeks on the John Muir Trail...WOW! The heaviest the pack ever was, with seven days of food and one liter of water, was 30 pounds. Even at this weight the suspension system kept me comfortable on the rocks and over passes. And it only got better as the pack got lighter.
I passed many PCTers with Mariposa packs (of all generations) and they all had great things to say about it too.
It's a little dirtier now but it held up great. Thanks. (Posted on 7/10/15)
Perfect multi-use light packReview by kzh
We have used this pack on several long-distance canoe trips, a rim-to-rim grand canyon hike, and a backpack train trip in Europe. Four users that range from 100 lbs 5'2" to 180 lbs 5'11".

It is extremely light and comfortable. It has put up with the abuse of airlines and in-and-out portages with no damage. The four different-sized mesh outer pockets are fabulous, allowing you to load what you need where you want it (and we love the easy-access SitPad in the frame). There is just enough space in the hip belt pockets for small camera, sunscreen, and a granola bar.

We were able to quickly adjust the size for the different users. We got a medium, along with both small and medium belts. There was no "useless" slack in the straps, which helps both with pack weight and with airline travel (no tangles).

The only thing we didn't like was the way the pocket on the lid works -- if there's anything in it, you can't easily access the main body.

At 9" x 12", the hydration pocket is ideally sized for the Camelbak 100oz mil spec antidote short hydration pack. (Posted on 7/6/15)
Might be the best pack on the marketReview by Kyle M. from Austin
Purchased the new Mariposa for a trip to the Olympic Peninsula at the recommendation of a friend. 8 days in the backcountry and literally could not be happier with this pack. Quality, construction and finish is excellent. Outside storage is the best I've seen. In the front mesh pocket, I had water shoes, rain jacket, teeshirt, jet boil, full 3L platypus and still had room to spare. Stored a large exped blowup pad and a fleece in the tall side pocket. Lower side pocket is perfect for large water bottle, and easy to access while pack is being worn. Inside I was able to fit a 2 person tent and large Bearvault side by side. Shoulder strap material is amazingly comfortable and breathed very well. Excellent hip belt. No hot spots on hip bones like other packs I've had.

Started trip at around 43 lbs and the pack carried it very well. First Gossamer pack, but definitely not the last. I am a fan for life.

Keep up the great work!

An absolute JOY!Review by Hiken' in AZ
Update: Since my first overnighter with the pack, I have taken it for 5 days on the AZT. Started on day one just shy of 33 pounds. Pack became a little lighter as I finished, but because I consistently carried 3 liters of H2O, it was only the food consumed that lightened the load. Even on day five, I was feeling great with this pack! No sore shoulders, no comfort issues at all. I even remarked to my hiking buddy that I just couldn't believe how great this pack felt on day 5! Pack shows no sign of wear. Love the large pockets as they made it very easy to stash hat / jacket as needed, or pull them back out when it cooled down. Ran into some rain. Only put on poncho when it really came down, but for the times that the pack was unprotected, no water seeped in. Could not be happier! (Posted on 4/26/15)
My first taste of GossamergearReview by munro277
Over the many years I've been backpacking I've owned 6 backpacks. I can honestly say this is the best backpack of them all. I've been using this pack since February and was surprised at how comfortable it is to carry.

I have been a big fan of hipbelt pockets for a while and was pleasantly surprised by these ones as they are a really good size. I like how both pockets can be opened while on the move.

Another good feature of this backpack is the construction. It is very easy to pack. I have had a difficult time getting my sleeping bag pushed to the bottom of other packs such as an Osprey pack I had owned because its design. The Mariposa has ample room in the main compartment for all your dry gear and food. I also can fit my dog's food and other gear.

My favorite feature of this pack is the number and variety of external pockets. There is one deep pocket on the side that will fit nearly all good packable shelters. The other side has two pockets. One I use to carry my pegs, water, and filter. I use the other to carry microspikes, snacks for the day, plus extra gloves. Backpacking in the UK, it is important to have easy access to these items as you are often hiking in poor weather.

On the rear of the pack is a huge mesh pocket which seems to be able to swallow so much gear. It really is amazing how much it will hold. It's a great place to dry off your shelter while on the move as well.

The only changes I'd like to see is a hook or hoop inside to fasten my car keys to and a bit more material in the top side of the lid pocket so that it's easier to get dirt and other debris out of the lid pocket. Both of these are minor details. All in all a comfortable and well designed backpack. (Posted on 4/25/15)
LOVE the pack!Review by Hiken' in AZ
This is my 3rd ultra light pack. I've tried REI Flash and Golite Jam = both were uncomfortable. Took the Mariposa out on first backpack with 25.6 lbs and can not believe how well it handled the load. This pack was as comfortable as my Gregory Deva, which I absolutely love (except for the weight). I had my BA Ethel, BA Seedhouse SL1, Thermarest pad, stove / fuel, water filter, down jacket and pants, wind jacket, poncho/tarp, 2 days of food, 2 Lt H2O, toiletries, change of socks, SPOT, phone/camera, map bag and still had room for more if needed. Everything fit inside the pack. The weight did not sag on my behind or pull on my shoulders as I have experienced with the other ultra light bags that I've tried. I did switch to the ULA hip belt simply because I like the larger pockets. Could not be happier with the pack. (Posted on 2/24/15)
Mostly happyReview by Walk the World for Love
I have used this pack now for about 5000kms (purchased early 2013). Overall I'm really happy with this pack, I wasn't sure it would hold up with my weight (sometimes a little over the recommended) and the treatment it gets, but it has so far. A couple of problems though...the shoulder padding where I pick my pack up has split right through, creating a gap in the strap. This is not an issue with performance or comfort, just one of quality and durability of the foam that was used. Also, one of the eyelets that enclose the cord for the lid straps popped and rendered the lid with only one functioning closure. Another negative...the zippers on the belt pockets of both sides have torn away from the stitching so I cannot open the zip fully and there is a hole in the pockets . This may have been caused by excess weight in the pockets but it happened very early on and I would've expected better quality. Gossamer Gear now have a new generation of this pack and these issues may have been addressed with their latest model???
A design feature I would've preferred is for the zip in the lid to either close toward the head or be at the back of the pack rather than at the side. As it is I cannot access this pocket on the move and I'd really like to be able to do that. NOTE FROM GOSSAMER GEAR : The shoulder strap is not to be used to pick up the pack when fully loaded - Use the attached haul loop. The pack being reviewed is a 4th generation pack, and several of the above mentioned issues have been resolved with the making of the 5th gen. Mariposa - Thank you for your comments (Posted on 2/23/15)
Great Transition to UL PackReview by BeeKeeper
This is my second Mariposa (4th and now 5th generation). Previously I had an adjustable off-the shelf big-box manufacturer pack, as well as a competitor UL pack. However, after receiving my GG Mariposa, I sold the competitor pack, and never looked back. The small fits my 16.5" torso just about perfect. The 5th generation shoulder harness is very comfy for my small frame. Hip belt and pockets are also a great fit. I have a severe sway back and having an adjustable stay has made a huge difference for me in pack fit and carry.

I love the large side pocket for storing my tent and ground sheet. The mesh outer pocket is great for carrying camp shoes or other items needed for same day. I don't use a stuff sack for my down sleeping bag and there is plenty of room for leaving it unfurled. Although it is rated to carry 30-35lbs, I most often carry around 18-22lbs.

This pack washes well. I just remove the stay and waist belt and throw it in my washing machine then hang to dry. It looks new after a good year of use, my gen 4 also looks new after 2 years of use. (Posted on 2/11/15)
AwesomeReview by Pipes
First thing I notice when opening the box.... WOW this bag is much more durable and built much better than I expected it to be considering it's weight. Normally there's a trade off in quality/durability when you want something this light. Not the case here.

Second, Although I am 6' tall my back measures just small enough to fit a med. That doesn't bother me because I like the little bit lighter weight and to wear my pack fairly high on my back. Although the pack is VERY comfy the shoulder straps are extended as long as possible in order for me to wear it. I am thick in the chest, ribs, and shoulders so that doesn't help but maybe a little more room to adjust the shoulder straps would be nice... after all they do include a clip so you can clip the excess strap material together so a little more length wouldn't really get in the way... plus trimming excess strap material is easy if it is in the way but adding is impossible. If I were any bigger this bag wouldn't work for me because the straps are just that short.

All in all I love this bag. It's insanely comfy when you use a sleeping pad as your back rest but also keep in mind if you sweat your sleeping pad will get wet and you must dry it before you sleep on it. The pockets are huge and the mesh is MUCH stronger than one would expect. Besides the short shoulder straps (for my big frame) I have nothing to complain about. Easily the best bag I've worn.

I'm 6' 215lbs I bought this bag with my own money and was not asked to do a review. This was done simply to help others make informed decisions. I have one trip on this bag so far but will be doing many more. I will continue to update my review if anything changes. NOTE FROM GOSSAMER GEAR : It is Very possible this customer would be better suited in a Large Mariposa at 6' tall. (Posted on 1/20/15)
Great UpgradesReview by Jen A
I started out with the original Mariposa and recently upgraded to this latest version. It keeps all the wonderful features that attracted me to the Mariposa in the first place (long side pocket and general comfort), but adds some great new improvements. First and foremost is the extra padding on the shoulder straps, which adds to the overall comfort of the pack. The straps also are narrower. All in all, the Mariposa is a great pack for people looking for a versatile and sturdy option. I love it! (Posted on 11/4/14)
Awesome Backpack!!!Review by HB Hiker (Youtube)
I have been very pleased with this model backpack. I started out with the original Mariposa Plus back in 2010, and upgraded in 2012 to that years version. The color and features have changed since then but from what I see its for the best. I've been on week long adventures with this pack and really pushed its limits. It has been with me on the top of Whitney, bushwhacking my way through the Sisquoc river and it even held my snowshoes while hiking in the winter. The pack has defiantly proved it self worthy. My load, depending on the trip, is about 25 to 30 pounds but I'm pretty sure I've maxed it out a couple of times. Still going strong! The new features since I bought my last Mariposa are very cool. The ice pick and trekking pole holders are a useful addition. I would recommend anybody that wants a comfortable light weight backpack to look no further! Gossamer Gear is quality, enough said! Thank you for providing me with a great backpack that holds up to my abuse. (Posted on 10/20/14)
Love My First MariposaReview by Thistle
I received this pack recently for my birthday. (Of course I did the hard work of researching it and picking it out!) I absolutely love it! It is only the 2nd pack I've owned, but I don't think I'll need any other pack for quite a while. I love the large main compartment. I managed to get my 20 degree top quilt, my 0 degree bottom quilt,clothes and food for a couple of days, hygiene items, and quite a few misc. items and had room for quite a bit more if needed. My hammock fit nicely in the large side pocket, along with my stakes. The 2 pockets on the other side-The bottom pocket: My 1 liter Smartwater bottle and my Platypus gravity works filter system. (Waterbottle easily reachable without removing the pack! The top pocket held: my cook kit and fuel bottle. The very roomy back pocket held all the rest! From my tarp to my repair kit, first aid kit, pack cover, rain coat, seat pad (homemade), flip flops, rain pants and various other items! The pockets on the belt are roomy and held snacks, a camera, insect repellant, my buck knife, lip balm, and a small tin of altoids! I am a" wanna be light" backpacker, not an ultra light one. I have been working on lightening my load, and getting this pack saved me about 3 pounds. I am aware of some other gear upgrades that I am willing to make that will ultimately save me about 5 more pounds. My perfect pack will weigh between 19-23 pounds with food and water included. right now I'm at about 26. Thanks to the Mariposa, I am well on the way to my goal! Even at 26lbs, I get a pretty comfy carry! Can't wait to see what it's like at a lower weight. (Posted on 10/4/14)
