Trion 38 - Solid pack for lighter loads

I used this pack for an overnight to try it out before getting into the snow. I am 5'11''. The torso is a little short and there is not a lot of structure to the belt, so it did not carry weight well. It did grate from a water protection standpoint, keeping my gear dry in a downpour. Overall solid pack, durable attachment points. I would only use it for lighter weight day-trips.

Great for multi-day hut-to-hut trek

I needed this size pack for the W trek in Torres Del Paine National Park in Chile. The pack is light weight, comfortable and sleek. No water bottle pockets, but I used it with at 2-liter hydration bladder which worked great. Could have fit a 3 -liter bladder if needed. It's more than a day pack but less than a full size back country back pack. Zippers and Buckles are durable and easy to use. Good access to stuff inside, without a lot of unnecessary pockets and accessories. I'm very pleased with it.

Trion 38

I love this pack for BC skiing and mountain adventures. I rarely use the full 38L, but the pack rolls down (like a drybag) for whatever size you need. I love the side zip for easy access inside.
