Thomas K.wrote a review of Mammut Trion Light 28L+ Backpack on January 20, 2019
Familiarity: I've used it once or twice and have initial impressions
I used this pack for mountain biking and hiking part of the AT in snow and it was comfortable and kept my gear dry. This was my second piece of gear by Mammut and I love their products. The roll top makes this pack very weatherproof. It is the perfect daypack and holds trekking poles nicely. I look forward to ice climbing and climbing Kilimanjaro with it.
