This backpack has been wonderful This backpack has been wonderful in keeping all my gear organized and compact. Taking it to the gym, it's not too bulky and taking it out to the crag, it has room for all my gear and more. Love the roll top closure and the side pocket access to get what I need

Great mid-mission pack This has quickly become my go to backpack for medium intensity days where I want a little extra room to bring more essentials, but don't quite need to extra room of a 45L class pack. This is a very well made backpack. It's not the lightest, but the tougher fabric has been holding up remarkably well. After 10 or so uses there are zero signs of wear other than some cosmetic s

Solid pack! This is a versatile pack. I’ve used it for a handful of long day hikes and couple weeks of backcountry skiing. It’s durable enough and I like the roll top. The runner-style shoulder straps are comfortable (we’ll see how they hold up).

Very Efficient and Comfortable The Mammut Trion 28 is a near-perfect balance between comfort, durability, and functionality. From the first wear, the ergonomic design stands out — the back panel, straps, and hip belt work together to distribute weight evenly, making long treks or climbs far less fatiguing. It’s incredibly lightweight yet remarkably strong, handling heavy loads without any sign of

Great mountaineering backpack I use this backpack regularly for my mountain adventures and for the one day climbs, this proved to be ideal. It's strong even carrying a lot of weight in it and it sits comfortably during the climbing itself.

Trion 28 Review I think this is a great pack. Lots of features and very comfortable. I love the top and side zips as well as the roll top feature. The shoulder straps are super comfy and I love the pockets on them as well. My only gripe would be the elastic on the chest clip can slip. Apart form that great.
