Feature-loaded and featherweight, the Trion 38L Backpack is ready for serious mountain days

What Our Gearhead® Experts Are Saying:


"The Trion 38L Backpack has become my go-to for ice climbing approaches and BC ski days because it carries a surprising amount of gear without the bulk — dual ice axe attachments, ski carry, and the roll-top closure mean I can load it exactly how the day demands. The shoulder strap pockets feel like a running vest and keep snacks and a phone accessible without ever stopping. For the weight, the tool attachment system alone is worth the price."


The alpine doesn't care how organized your pack is until the moment it matters — when you need your ice axe in hand at the top of a couloir or your skins out fast on a ridge transition. The Mammut Trion 38L Backpack is built around those moments, combining a versatile tool carry system with a roll-top closure that adapts to exactly what you're bringing, whether that's a half-day summit push or a full ice climbing rack.


Mammut's CONTACT V Frame keeps the load close and controlled without the stiffness of a traditional framesheet, distributing weight comfortably on long approaches while leaving enough mobility for technical terrain. The roll-top main compartment expands when you need the volume and cinches down tight when you don't, and the side zip provides fast access to gear buried mid-pack without unpacking from the top. Two ice axe attachment points handle a full alpine kit, trekking pole carry frees your hands on the descent, and ski and snowboard carry options extend the pack's usefulness into winter objectives. Mesh shoulder strap pockets — sized generously enough to carry real items — keep the essentials within reach without breaking stride.
