Gossamer Gear Mariposa 60 Overview

The ultralight world is, by nature, a place where you cut items out. Luxuries and comforts and even functionality all get sacrificed to the great base weight god. While this will always be true, there comes a time when you want some of that functionality back, but you don’t want it to cost you.

Enter the Gossamer Gear Mariposa 60. This ultralight backpack somehow manages to include all tGossamer Gear Mariposa 60 hose pockets you thought were long gone; the belts, straps and buckles you said goodbye to; and thick, padded comfort that was thought to be impossible if you were truly going light. The Gossamer Gear Mariposa 60 retains all these features while remaining ultralight, hovering around a scant 2 pounds empty depending on the size you need.

It’s not just the triumphant return of what was once lost to the ultralight world, but the cleverness of design that makes the Gossamer Gear Mariposa our Classic Pick for the Ultralight Backpacker. Well, that and the price, which is middle of the road despite high quality materials, incredible craftsmanship, and legendary customer service.

Gear Review of the Gossamer Gear Mariposa 60

Origins: Easing You In

For me, the best part of going ultralight is that first hoist onto your back. I dread the “put it on test” for normal backpacks — you lift, you let it settle, and then you realize you have a long way to walk and nothing is getting much lighter.


The Mariposa’s first lift for me was on the trail back from an overnight in the Sespe Wilderness. In order to test the unisex feature of this pack (the Mariposa fits men and women) I took it to the desert with my partner. We packed our heaviest items in the Arc’teryx Altra 65 and the lighter ones in the Mariposa, switching things along the way to get the full range of weight-bearing possibility.

That first lift was a dream. We clocked the pack in around 20 pounds, well below the Mariposa’s recommended maximum of 35 pounds, and the typical weight for ultralight backpackers while carrying water and food for a short trip.


The Mariposa loaded up.

The Sepse was hot, dry, and stunning in the way a desert stuck in the middle of a years-long drought must be. Over the long, rolling miles the Mariposa hugged my back. It soaked up ample sweat, kept the load on my hips, and was adjustable to dial in the perfect carry.

Revelation: The Moment I Knew

Due to the fact that two people walked in the Mariposa’s shoes on this trip, I only think it’s fitting to illustrate two moments.

The first comes from my partner who, after two miles into our trek, asked if we get to keep the backpack. We do not. She was dismayed, to say the least.

The Mariposa has this incredibly attractive combination of elements that make it simple and desirable. This was obvious to her after couple miles. Pulling a water bottle from the side while hiking is easy, as is grabbing energy bars and an oversized smartphone from the hip belt pockets. Adjusting the pack at the waist, the load lifters, and sternum strap were all done in a cinch, too.


It’s more than functionality though — there’s the look and feel of the pack. The Mariposa is almost cheery it’s so light and small, yet it can haul a serious load for an ultralight backpack. It looks and feels great to the point that, once you hike with it, you want one.

The second moment, and my own, came that night as we broke out a deck of cards so I could get destroyed in Gin Rummy. Cards are a luxury, but one I never embark into the wilderness without. A little downtime at the end of a long hike is perfect, especially when you’re traveling with a loved one or group.

Typically, at night in the tent, it’s hard to find a flat surface for cards. The Mariposa just happens to have an easily removable back panel, called a SitLight pad. It’s a dimpled foam pad that is quite supportive when worn, but it’s also a sit cushion when removed. The ultimate in ultralight multi-use, right?


The SitLight pad slips into the back mesh easily.

Well, it also serves as the perfect playing card table.

It may be a simple moment of revelation, but a pack that utilizes every last bit of its feature set is a winner in my book.

Digging Deeper

A backpack like the Mariposa has a full grocery list of excellent features, so I’ll just focus on a few main ones.

The pockets. Oh, man. Gossamer Gear threw seven exterior pockets on the Mariposa, six of which perform wonderfully.


Pockets in use.

The super long side pocket is perfect for a tent and tent poles, which makes setting up and tearing down simple.

The other side of the pack has two pockets, one over the other. The lower one is meant for a water bottle, and fits Nalgenes, Smart Water bottles, and anything else you may have. The pocket above that, though, is unique in its placement and size. Many people fit their ultralight cookset in that pocket, which makes meal-time a breeze. We used it to store easily accessible food.

The stretch mesh pocket along the back is really the best pocket, though, because of how huge it is.


You can fit your rain cover (trash bag for the win), a rain shell, an extra warm layer, food, etc. in there. It’s bigger than you think, and keeps the gear you need on the outside, rather than the inside.

Moving onto a different feature: the load lifters. Many ultralight backpacks these days don’t have load lifters because companies don’t believe they are needed based on the weight you’re carrying. I disagree.

Load lifters to me have always been about securing a more comfortable fit, and that’s never a bad thing. The load lifters on the Mariposa allow that adjustability so both my partner and I could dial in the pack to fit us best, making a single pack versatile to many body sizes and both genders.


Finally, there’s the main compartment. It’s huge. Just a single chute from top to bottom, standard for most ultralight backpacks. However, I loved what Gossamer Gear calls the “Over-the-top” closure, which is not quite a roll-top, and definitely not a drawstring.

You clip part of the top together, then fold the rest down and clip it into place. The pack always looks sleek like this, and it expands when you need to lug more (or bigger) items.


Foam pads line the back, hip belt, and shoulder straps. Ultralight bliss.


One trek is not enough to know if the Mariposa would survive Mordor, but the fabric is extremely high quality for being so lightweight. If you’re looking for the most durable thing on the planet, check out the Hyperlite Mountain Gear Southwest 3400.


It’s as if elves made the the Mariposa. Not Keebler Elves, but Lothlórien elves. It’s grey, subdued, and extremely light. Somehow a unisex backpack has been transformed into a sexy, versatile object. It can only be the elves.



With all that good comes a bit of bad.

First, the pack doesn’t breathe as well as I’d like. We did hike in a desert environment, and I do tend to sweat, but that sweat pooled in the dimples of the SitLight pad. It wasn’t critical, but I noticed it and wished it vented sweat better.

Second, the hole for the hydration port is really difficult to slide a tube through. I used a CamelBak Antidote reservoir and had to dismantle the nozzle end in order to get it through. This would become frustrating if I had to take it out often on the trail, so I would probably have to jerry-rig my bladder setup. That said, most Ultralight backpackers already do this.

Third, the zippered top pocket was a struggle to use when the pack was near capacity. The Mariposa is 60 liters, which means it’s huge for an ultralight pack. This also means it’s not designed to be totally filled up, because the Over-the-top closure cuts off the last 5-10 liters of the pack. It still works when it’s that full, but isn’t ideal.


The zippered pocket along the OTT closure, often used to store maps, a compass, or headlamp, is pulled very taut when you have more gear.

Final Word

Unisex sexy, the Gossamer Gear Mariposa 60 redefines what you can take on an ultralight backpacking trip. If you are a master organizer who wants easy access to your goods while remaining lighter than air, this backpack is for you.

    I purchased the GG Mariposa pack couple of years ago and frame wires started to come out at the bottom from the very beginning due to the lack of the durability of the material. I tried to fix it myself to no avail. Then I wanted contact GG customer service and but couldn’t locate a phone number on their website. Then i filled out the online form and no one got back to me regarding repairing the pack. Then i went on their website and wrote a review giving the pack only 3 starts due to bad customer service and they didn’t post my review on their site. Looks like they only post reviews if you give them 5 starts. I am very much disappointed with the customer service and will never purchase anything from Gossomer Gear. I found a great to pack the Mariposa. Granite Gear Blaze!!!

    1. Daniel Zweiersays:

      Hi Harpreet,

      Sorry to hear about your experience with the GG Mariposa. How much weight did you try to carry in it when the frame wires came through the bottom of the pack? It’s definitely not built for loads above 25-30 pounds.

      Your story about GG customer service is really unfortunate. However, that’s not at all the case we’ve had with the company. Some of our staff know the founder, and have always experienced timely responses for general inquiries, issues with product, or even replacements. Not sure what happened for you, but we still stand behind Gossamer Gear as a company and this pack for ultralight loads.

      The Granite Gear Blaze is also a fantastic pack, and we’re glad you found something that works for you!

    I purchased the Mariposa 60 last winter and used it this summer (2021) on three one week backpacking trips. There was some good news and bad news. The good news is that I am 71 so I really appreciated the light weight of the pack. I was able to carry six and one-half days of supplies (including dry dog food for two trips) with a maximum pack weight of only 32 pounds. This included a BV450/BV500 bear vault on all three trips. The trips were a combination of off and on trail – a good test for the pack (and me). The pack was very comfortable. The bad news is the durability. After the first trip I noticed three small tears in the bottom of the pack about the size of a finger. I am not certain when this occurred, but it might have been from a slip on a talus slope. Clearly, the bottom of the pack is vulnerable to slipping and falling as well as just the wear and tear from resting on a rock/ground by the trail. There is no warranty for durability issues in which under their warranty page (in bold) is written: “Gossamer Gear does not, however, warranty products against materials or fabric failure due to durability issues.”. That it is in bold probably indicates that I am not their only complaint. My suggestion is to sew a material over the bottom of the pack (like nylon cordura) which would reinforce the exposed part of the pack, but add minimal weight. I submitted a review to Gossamer in which I recommended the pack, but only gave it three out of five stars because of durability, but this was rejected. However, they were very responsive to my complaint by email.
