    Climb up, ski down, repeat.

    You'll climb a mountain in the summer with climbing shoes and a tank top, and you'll climb the same mountain with winter's snow underneath your backcountry skis; the only thing that stays the same is Mammut's Trion Light 38 Plus Backpack. Mammut made this multi-purpose backpack incredibly versatile for year-round mountaineering missions ranging from fast-and-light alpine climbs to day-long backcountry tours. Its Motion T-Frame offers plenty of stable support for long approaches, and you can remove it when it's time to climb a few multi-pitches. This backpack also boasts plenty of carry systems specifically designed for skis, ice axes, trekking poles, climbing ropes, hydration reservoirs, avalanche safety gear, and more.

    Solid pack that can ski tour

    • Familiarity: I've used it several times

    Nice and light, easy to modify to what the day holds.
    The "wet pocket" avalanche tool pocket is a little shallow for most tools.
    I don't feel like the pack is truly 38L yet if its large enough for overnight gear.
    All in all I think this a great day climbing pack for 4 season use

    Great light pack

    • Familiarity: I've put it through the wringer

    Ive used this pack twice on moderate ice climbing routes. Baker North ridge, and Kautz. It has enough room to comfortably hold climbing and overnight gear. The shoulder straps feel thin, but don't cause any discomfort. The two main compartments is a cool idea, but is less functional on a pack this small. Theres also a buckle missing from the top of my pack, unless I missed it the 16 times i looked for it. (theres a buckle and strap to hold the main compartment together/ strap ropes, and another strap to close the lid, but no buckle???) One other small gripe, the built in straps for ice axes is either too small for two climbing axes, or awkwardly spaced apart. aside from those small issues, still loved the pack, great performer.

    This pack rocks!

    • Familiarity: I've put it through the wringer

    I've used this pack on some multipitch routes and it has plenty of space for my puns. The Keeper strap is an awesome feature as well as the relocatable lid.

    Good size and design for ice

    • Familiarity: I've put it through the wringer

    I've been using this model for two years now as my "up and over" bag on longer ice climbs where we're hiking off from the top (e.g., Cannon Cliff in NH). It's my choice because it's lightweight and compact, but has enough space for the layers/etc you need during cold weather climbing. Also, the lid is easy to remove, so I can take that off to lower the profile/weight even further during climbing. My pack is from 2-3 years ago and it doesn't have the attachment points for more modern ice tools, so I'd only give it 4 stars--but Mammut has addressed that with the newer version. Also, I'd ideally have a two buckle closure system for the lid of the pack just to keep it aligned easier, but that's not a huge issue.
