Gents I was wondering what backpacks, preferably day packs <60L, you are using or know of that are well designed and sturdy. I have had a look at K-way and first ascend bags and none strike my fancy.

The use will be as a Go-bag, but not in the normal sense, it will double as a short distance (less than 15km) hiking bag so a hydration friendly design is preffered. It basically will compliment my "extended stay box" that stays in the vehicle.
Thanks
