Looks and feels great, won't absorb water, not noticeable while hanging off pack, and kept me above water in class 3+ rapids... can't really ask for more.
The pocket is big enough for a emergency bivy and firestarter. it also fits tight enough that clipping stuff onto it doesn't cause any slumping, the grippy stuff is great for hold. Oh, and after bushwhacking through alder and devils club thickets it never ripped!
Im 6', 165 and a M fits snugly
