I absolutely love this pack, I can fit all of my essential gear into it and still have tons of room left over. Recently tested it out on a 4 day winter overnighter, had no problem fitting my snugpak elite with bivy inside of it, a change of clothes, etc. and it held up perfectly against the briars and brambles everywhere on the trail. The suspension system makes this pack comfortable even when stopping and jumping over and under downed trees and through snow and mud. Best pack Ive used.
