Mammut Trion 38L Backpack Arumita/Marine

What Our Gearhead(R) 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.
