I have the Stoney Creek 2 in 1 bum/daybag. Works great for bush hunting, carries enough gear for a full day hunt plus room for a plenty of meat. I collapse it down to a bum bag for half day hunts or full day hunts in summer. Most of the time the top pocket only has my jacket & binos in it when I am not using them. The rest fits in the bum bag section (Including 1L water). Its comfy to wear as long as its packed correctly and has a very low profile which is great for real thick country.
I have another 40L pack I use for alpine country (Tahr hunting, etc) as the 2 in 1 just can't hold enough gear for those trips.
