Badlands backpack! Hands down the best pack you can get.
http://www.archerywarehouse.com/Backpacks.html I own the super day pack shown here. I put my bow on the pack and off I go

If you dont want to pay that much I just saw a "Texas Tropy Hunter" pack at Academy that had a water bladder, looked quiet, roomy and had a headlamp attatched to it as well. Looked nice.
Didnt have a place to attach your bow though

Can't go wrong with the Badlands.
