Gossamer Gear Mariposa 60

4.7(450 reviews)

The Mariposa 60 is Gossamer Gear's signature pack, famous for its asymmetric pocket layout — one giant over-the-shoulder pocket that holds a tent, plus six more — and a removable back pad that doubles as a camp sit pad. It's the organized person's ultralight.

Pros

  • The seven-pocket layout is the best organization in ultralight — fans say they touch the main compartment twice a day, morning and night.
  • The tall side pocket holds a full tent separately from dry gear, the single most-praised design choice.
  • The removable back pad doubles as a sit pad, saving carrying a separate one.
  • Robic nylon at 100/200 denier hits a durability sweet spot documented across thousands-of-miles reports.
  • Hipbelt sizing is independent of torso sizing, giving semi-custom fit from stock parts.
  • Carries 30-35 lbs comfortably with the stay in — honest rating per long-term reviews.
  • The Austin-based company's customer service and repair culture draw consistent praise.
  • Fits a BV500 horizontally at the top of the bag, which many 60L UL packs can't.

Cons

  • The asymmetric layout is polarizing — packing balanced weight takes practice and annoys symmetry-lovers.
  • The foam back pad ventilates poorly and soaks sweat on climbs.
  • The single aluminum stay twists under 35+ lb loads; it's not a heavy hauler.
  • Mesh pockets abrade in brush faster than solid-face rivals.
  • No top lid and a floppy over-the-top strap system that takes fiddling to compress well.
  • Fixed torso sizes with online-only sizing risk.
  • At $315 it's priced above the Circuit while carrying slightly worse at max load.
  • The hipbelt foam softens noticeably after a full thru-hike, per multiple finishers.

The Gorilla 50 is the Mariposa's smaller, symmetric sibling — 50 liters, under 2 lbs, and the classic 'second pack' people buy once their kit shrinks. It keeps the sit-pad back panel and Robic durability in a cleaner silhouette.
