Introduction
The Gossamer Gear Mariposa is a 60-liter internal frame pack that falls somewhere between an ultralight pack and a medium-weight pack capable of carrying heavier loads. It is considered a high volume ultralight backpack. Gossamer Gear recently re-designed the hipbelt with the purpose of improving load distribution and increasing pocket size.
I’ve recently begun enjoying treks with my children. For this reason, I’m carrying a little more weight than I once did. I tested the Mariposa 60 with this use in mind.
I was impressed by the features, functionality, and comfort of this pack—especially as the design itself is simple. The pack is spacious and has seven pockets. It met my needs while trekking and kept my gear accessible and organized.

Description of Field Testing
I tested the Mariposa 60 on a multiple-day hike in Montana’s Beartooth Range in mid-July. My base weight for the trip was twenty-two pounds. I hiked and camped at around nine thousand feet elevation. The weather was typical of the area and season: sunshine with a few overnight showers and one large storm with rain and hail.
Performance Assessment
My performance assessment of the Gossamer Gear Mariposa 60 will address the following items:
- Finish Quality and Design
- Fit and Comfort
- Functionality
Finish Quality and Design
The Mariposa 60 is a simply designed lightweight backpack with well-thought-out features. The fabric used in the Mariposa 60 is heavy in high-abrasion areas and lighter where possible to save weight. The quality of stitching and seams are on par with any other high-end backpacking manufacturer. The pack is aesthetically pleasing and seems designed to last.
Fit and Comfort
Gossamer Gear offers both the pack and hipbelt in multiple sizes so you can get the fit dialed in with precision. The result was a pack that felt just right on my six foot one, one hundred and seventy-pound frame. It hugged my body and felt secure.
When I first tried on the pack I felt like the shoulder straps were too close together. I felt some pressure on the outside of my neck. But once I loaded the pack the feeling vanished and never returned.
A lack of breathability is a common complaint about this pack. Gossamer Gear has created a combo internal pack frame/sitting pad designed to increase airflow. The pad, called the Air Flow SitLight Camp Seat, is designed to slide into the pad pocket of the Mariposa 60. Ostensibly this adds structure to the pack and increases breathability. I didn’t notice my back being less sweaty while testing the pack with the SitLight seat inserted. However, it did seem to increase air flow slightly.
Functionality
Gear accessibility is the main strength of this pack. I’m used to a very simple pack design: one main compartment and two pockets. So it was a novel experience to use a sub-two pound pack with seven outside pockets. The quantity and location of the pockets is a plus for a backpacker who enjoys organized gear systems.
The water bottle pocket (right-hand side of pack) is technically accessible without removing the pack. However, I’m flexible and use soft-sided water bottles, and I still struggled to reach it at times.
The large hip belts are ideal for gear storage and organization. I kept my map, Garmin Foretrex 301, headnet, and snacks all in one hip belt pouch. In the other, I stored my lunch, allowing me to eat as I hiked.
The mesh pouch on the back of the pack is spacious and lets you expose wet gear to the air for quicker drying.
Commentary
The Mariposa 60 is more pack than many ultralight backpackers want or need. On trips that necessitate more gear or volume than usual (like when hiking with children), this pack excels. The large and numerous external pockets make for gear that is easily stored and quickly accessible. The recently re-designed and enlarged hipbelt pockets were a winning feature in my book.

Companion forum thread to: Gossamer Gear Mariposa 60 Backpack Review
The Gossamer Gear Mariposa 60 is a high volume ultralight backpack that is capable of carrying heavier loads.
Thanks for posting. I looked at a previous edition of the Mariposa and elected to stay with my Osprey Exos 58 of 2015 vintage, even with its tiny hipbelt pockets. The compelling feature of the Exos is the Airspeed suspension which ventilated so well as to put to shame all other packs I’d tried. Using the Exos, the back of my shirt never wetted through while hiking the PCT in July, August, September and October of that year. While the “58” may be a bit heavier at 40 or so ounces, Airspeed carries the day.
I mused that you struggled to access your water bottle without removing the pack. I haven’t the flexibility to deal with anything worse than the Osprey’s easy bottle access.
The Mariposa seems like a winner on most other points.   The Osprey Exos works for me.
I need to get out more with my Exos. Cheers.
Yeah, the pack definitely looks good for those carrying between 10-20 pounds of base gear. I never had a problem just using water bottles in my other GG packs. However the HMG Southwest simply cannot be done, reasonably in my book. Osprey seems to have them beat slightly, but, I lost a water bottle using it. Also the Gorilla. While it holds stuff securely, I also lost a water bottle using it, too.
Anyway, thanks for a good review of the newer models!
I wouldnt even consider the mari and the exos in the same class. The exos is deffinately a bomb proof pack and I like the airspeed, my only complaint is that it is much more hourglass shaped and the top really pushes forward, almost pushing your head forward. The mariposa can really cram all you could ever want, I dont think it carries well over UL, and the way it’s designed you can get some awkward loads if your not dialed in. But I will say the mariposa will almost eliminate the shoulder pressure if you have the waist belt nice and snug. 10-12 range base and add in whatever you need the mariposa cant be beat, the exos is currently my winter pack that can carry the weight better. Just imo… for really cold deep winter I still like the atmos 65. You could put a car in that thing.
