I have a green military pack, it's got 2 big pockets inside. I don't even remember where I got it I've had it so long. I used it all the time for years when I was still hunting from trees. It carried everything for setting up except for the stands themselves. I started using it last deer season as my main day pack, I can't see it ever wearing out. As a bonus, it looks cool with my plaid wool hunting shirts, lol.
Those Classic Bowmen packs look very nice, but I could get a few dozen wood shafts for the price.
