A few years ago I bought myself a small backpack. The usual day i would look inside and find... Doe estrous, grunt call, hand warmers, extra flashlight, batteries, water bottle, spare gloves to gut deer, rangefinder, and clothing and boots scent free spray. extra box of slugs or any ammo for gun. If im bow hunting maybe and extra release. Nothing crazy just the essentials to be in the woods all day and maybe a few extras. On my belt I carry 2 knives, one for gutting, other for clearing twigs and sticks away. and always always always a flashlight. Alot of people criticize about the back packs but i think they are wonderful. Carrying anything other than the gun can be dangerous and when your walking long distances in rough terrain slipping is common and its is very very easy to lose stuff. the backpack reassures you that everything you brought is still there!
