Trion 35L Backpack

The Mammut Trion 35L Backpack is ready for your technical days in the mountains.  It features numerous attachment points and organization options, including a place to secure your trekking poles or ice tools. The entire back panel zips open for full access to your layers, food, water, and other gear, while a front pocket secures and organizes your avalanche safety equipment. A strap below the brain evenly secures your coiled rope across the pack, expanding your gear-carrying capabilities so you don't need to bring an extra rope bag.

  • Daypack features plenty of space for climbing
  • 35-liter capacity for technical day trips
  • Back panel zips open for easy access to gear
  • Front pocket secures crampons or avy gear
  • Excess load strap secures your rope

My favourite crag pack so far!

  • Familiarity: I've used it several times
  • Fit: True to size

I absolutely love this pack. It's served me well through ADK approachs and weekends at the Gunks. The zippered opening on the back of it is a game changer. It's sturdy, it's got enough bells, whistles, and pockets that are useful but not so many as to be a problem finding what you need.

Weight distribution is a sinch, ropes fit over the top perfectly. And its easy to life off the ground and shoulder.

My only gripe is the hydration pouch is so low in the pack that a standard length hose forces me to turn to my left and back to drink from. I use a HydraPak Force 2 liter.
