There's a lot you can do in a day.
Mammut made the Trion Zip 22 Backpack for day-long mountaineering adventures like multi-pitch climbs or ski tours with rappels. Its Contact Vent suspension system uses narrow, climbing-specific padding at the back panel, shoulder straps, and waist belt, and Mammut set the waist belt higher in order to accommodate harnesses more comfortably.
The Trion has an internal sleeve for hydration reservoirs and external straps for climbing ropes. Since the rope isn't in the pack, the Trion has enough room for a rack and climbing gear or avalanche safety essentials. Mammut reinforced the Trion's three-point haul system to carry up multi-pitches confidently. There are two stable carriers for ice axes, external and internal lid pockets, and compression straps to secure your gear on the ascent.

- Q & A
I was at home, literally 20 feet from the door when an âattemptâ to deliver my package was made. If you actually believe an attempt was made. Obviously I donât. So thanks Backcountry, for selecting a poor shipping option...really appreciate it.
Good little leaders pack
- Familiarity: I've used it once or twice and have initial impressions
Great little fast and light leaders pack. Great tool attachment system - should accommodate both more traditional tools as well - and the side straps hold a set of crampons well. If you pack carefully you can fit a full days worth of gear for those long approaches climbs where you don't want to leave a pack sitting at the base of the route, or want to go as light as you can.
The Summit and Beyond
- Familiarity: I've put it through the wringer
About a year ago I began searching for a pack with the following criteria; able to strap skis to, light low profile for summit attempts, small waist belt that wouldn't interfer with a climbing harness, no wasted features like multiple pockets or pen holders. I selected this pack and waited for about a year to write this review so I could test the pack in all the areas I intended to use it. I have since used this pack for skiing, multi pitch trad climbing, carry on bag to fit under an airline seat, and day hike pack. I can now say the Trion Zip 22l does it all. I have strapped skis to the side of it, 60 meter rope to the top of it, and all kinds of assorted gear inside. I like how the packs waist belt sits high so not to interfer with a climbing harness. The padded shoulder straps are comfortable and come with a chest strap. This bag is made to simply stuff things in on the go. It does have a small external pocket to place things in and a mesh pocket inside the lid as well. Works great as a summit pack. I have not tried the ice axe holders but for what I can tell they would work well. If you need a little more pack the Trion 28l would be good. The 22l keeps me from hauling more gear then I really need on a day climb, summit attempt, or a day on the slopes. For my criteria this pack has met and acceded all my expectations.

This is not a quality bag for day hikes at all. access to water and necessary items is sub-par. The straps are insanely cheap and make for awful weight distribution. If you were walking around campus or needed a bag to go to the farmers market in the city.... sure..... if you actually wanted to USE the bag.... get a different bag. One star - a guy said it was a good looking bag at the trail head LOL
Can you strap skis to this?
I'm looking for a climbing pack that can double as a bag for grad school. I know there's no laptop sleeve, but does anyone know if it could accommodate a 13" laptop? (Plus a couple books, jacket, etc?) Is this more robust than Patagonia Ascensionist? (which is a great pack but only for gear not books.)
Urban style packs just don't do it for me and can't cross over well into climbing or backcountry, so I'm hoping to find a compromise.
For what it's worth, I have an older Trion Light 28, and my 13" MacBook Air can fit in it. If there were to be any issues fitting it into the 22, the limiting dimension would probably be the width of the bag.
