Upland hunting packs

[nitinleew]

I want to get an upland hunting pack for pheasant/grouse hunting...I'll be hunting in British Columbia for grouse and in Alberta for Pheasant and other upland birds...I want a pack that can carry water for my two labs in the BC mountains and in Alberta..along with carrying birds snacks and all of the other goodies....I saw this one and I like it:

Any suggestions on the packs out there and what I should be looking for would be most appreciated.....
