Choosing the right backpack is one of the most important decisions any backpacker can make. After all, your pack carries everything you need to stay safe and comfortable on the trail. While I typically prefer smaller ultralight packs for most of my adventures, there are certain trips where extra capacity and better weight distribution become essential.

That’s exactly where the Gossamer Gear Mariposa 60 shines.

After using one of the earlier versions back in 2020, I walked away disappointed. Although I loved the pack’s organization, there were several design issues—especially the load lifters—that kept me from fully enjoying it. Eventually, I stopped using it altogether.

Fast forward to today, and Gossamer Gear has made several meaningful improvements to the Mariposa 60. After putting the newest version through real-world testing on demanding backpacking trips, including the Pennsylvania backcountry and the Uinta Highline Trail in Utah, my opinion has completely changed.

Built for Heavy Loads Without Heavy Weight

The Mariposa 60 is designed for backpackers who occasionally need to carry larger or heavier loads while still wanting an ultralight backpack.

For me, this pack really shines when I’m carrying:

• Eight or more days of food
• Winter backpacking gear
• Snow travel equipment
• Extra luxury items like a backpacking chair
• Loads between 30 and 35 pounds

Despite offering 60 liters of storage, the pack weighs just over two pounds, making it one of the lightest backpacks in its class.

What Changed Since the Older Version?

The biggest improvement—and the reason I now recommend this pack—is the redesigned load lifter system.

The older version simply didn’t transfer weight effectively to my hips. Instead, much of the load remained on my shoulders, causing discomfort during long hiking days.

The new design completely changes that.

With the updated frame geometry, the load lifters finally work the way they should, helping move weight into the frame and down to the hip belt. On my Uinta Highline trip, where I carried more than 30 pounds that included over a week’s worth of food, the difference was immediately noticeable.

The pack carried comfortably mile after mile.

Outstanding Organization

One thing I loved about the original Mariposa—and still love today—is its organization.

The large front mesh pocket provides plenty of space for gear you need throughout the day.

The oversized side pockets easily hold water bottles, cooking gear, or other frequently used equipment.

One of my favorite features is the tall asymmetrical side pocket. It’s incredibly versatile and easily carries shelters, trekking pole tents, fishing rods, or other long pieces of gear that can be awkward to store in traditional backpacks.

Having dedicated storage for these items keeps everything organized while making camp setup much faster.

Comfortable on Long Days

Comfort becomes increasingly important when you’re hiking all day with a fully loaded backpack.

The Mariposa’s shoulder straps provide excellent cushioning without feeling bulky, while the redesigned hip belt distributes weight efficiently.

I was especially impressed with the pivoting hip belt.

Although it’s a subtle feature, it allows the pack to move naturally with your body instead of fighting your stride. Over long days on the trail, that translates into less fatigue and a much more comfortable hiking experience.

My Only Real Complaint

No backpack is perfect.

If I could change one thing, it would be the pack’s top closure.

Personally, I prefer roll-top backpacks because they compress gear more securely and make it easier to stabilize the load. The Mariposa uses a traditional flap closure instead.

While this isn’t a dealbreaker—and it performed well throughout my testing—I still prefer the flexibility of a roll-top design.

Who Is This Backpack For?

I wouldn’t recommend the Mariposa 60 for every backpacking trip.

Most of the time, I personally use a 40-liter backpack because my gear is relatively compact and lightweight.

However, when I’m carrying heavier loads, longer food carries, winter equipment, or bulkier gear, the Mariposa becomes my first choice.

It’s an excellent option for:

• Thru-hikers
• Section hikers
• Winter backpackers
• Sierra Nevada trips with long resupply intervals
• Backpackers carrying bear canisters
• Anyone who occasionally needs to carry 30–35 pounds comfortably

Final Thoughts

After spending significant time with the newest version of the Gossamer Gear Mariposa 60, I can confidently say it’s a dramatically improved backpack.

The redesigned load lifters, comfortable suspension system, excellent organization, and thoughtful storage options have transformed it into a pack I genuinely enjoy carrying on longer adventures.

While I still prefer smaller packs for lightweight summer trips, the Mariposa 60 has earned a permanent place in my gear collection whenever bigger adventures require bigger loads.
