A versatile pack for any alpine endeavor.

Mammut's Trion Guide 45 + 7 Backpack caters to the four-season climber who isn't easily dissuaded from alpine activities once winter blows in. When the summer months lead you to high elevation granite routes, the Trio Guide will carry everything you need for the ascent with a rope fixing strap under the lid, daisy chain gear haulers, and gear loops at the removable hip belt. The hip belt allows you comfortably wear a harness with the pack still on. Once winter makes you switch out your approach shoes for a pair of ski boots, the Trion Guide will remain on your gear list with a grip of ski-friendly features like the side ski carry straps, two secure ice axe loops, and a large main compartment with both top and side access points for when you need to access avy gear quickly.

Unanswered Question

Where would be the best place to strap on either snowshoes or crampons to this pack? Or would there be a better pack for snowshoes/crampons?


Love the Color, LOL

  • Familiarity:I've used it once or twice and have initial impressions

I summit Chola Mountain with the Mammut Trion Guide. I have used it 16 days. I think it's little small for Alpine Mountaineering,maybe 50L is better。

in the Summit day I carry it have 19 hours,I don't felt any Uncomfortable,so I think it's prefect to help me finish this climibing mission。

if the side belt more longer is better ,I have thick pad,it's hard to bundle on the side,so i change a thin pad。

ps:forgive my poor english

Would this pack make a good all around crag pack or is it more specialized for mountaineering and alpine climbing?

Hey Kai,

You are correct in thinking this is more suited to mountaineering and alpine climbing. This bag could certainly work, but many crag-specific packs are much tougher to stand up to that type of daily abuse. The most durable fabric on this pack is 600Denier on the base, where something like this Black Diamond pack has 1200Denier all-around -

Another option from Mammut, standard rope bag might be all you need. The fold-out mat makes for a nice belay area.
