Gossamer Gear Mariposa Backpack

The PVT frame system is designed to pivot with your hips as you walk, which prevents the pack from fighting your natural gait. It offers a more dynamic, fluid carry compared to rigid internal frames, making it particularly comfortable on uneven terrain.

Yes, 60 liters is the sweet spot for most long-distance hikers. The main compartment holds your core gear, while the extensive external storage suite—including the signature large mesh pocket—is perfect for stashing rain gear, snacks, or wet items you need to access quickly.

The back panel doubles as a closed-cell foam sit pad that you can pull out during breaks. It provides essential structure and cushioning for the pack while serving as a convenient, dry seat when you're resting on the trail.

The pack uses a combination of 100D and 210D Robic nylon, which balances weight savings with necessary abrasion resistance. While it's not as thick as heavy-duty expedition packs, it is plenty robust for standard trail use if you aren't bushwhacking through dense, thorny terrain.

The back panel design prioritizes comfort and load transfer, but it is not a fully suspended mesh back. While it offers decent airflow, you will still experience some contact with the pack, so it's best suited for hikers who prioritize a stable, close-to-body carry over maximum ventilation.

Gossamer Gear offers the Mariposa in multiple torso sizes, so it is crucial to measure your torso length accurately before ordering. Because the frame is integrated, you cannot adjust the torso length on the fly, making proper sizing essential for the hip belt to sit correctly on your iliac crest.
