Familiarity: I've put it through the wringer
I use this on all my long day - hikes and I tend to bring a lot of things. This pack holds perfectly to my body and the large back panel keeps my back nice and dry while hiking. I love most that there are many straps to really synch down everything. I can easily strap down my extra layers on the outside of the pack as I hike. In addition the water reservoir works great. The only issue is that the water pipe is a little difficult to clean sometimes and it turned a weird yellow color after I washed it a few times. Still my favorite day pack.
