Am I just the odd hunter or what ? I have a decent pack that is 1950 cubic inches.I was looking to get something a bit bigger to handle an extra hat,gloves,maybe sweatshirt,rain suit when necessary,spotting scope,lunch,thermos and 2 water bottles.All the packs I have looked at go from my size up to maybe 2100 ci and then jump up to the big backpacks.Anything out there around 2500 ci so that I can comfortably go out all day without trying to stuff everything into a smaller pack and then fill my pockets ? Modular would be nice for the hot days when extra water bottles are needed.
