The Bushcraft Pocket is a simple concept, it's an extra bag that folds and rolls up to be carried on your belt or on your pack strap. We used a heavy waxed canvas backer with a brass snap and heavy cotton-canvas webbed belt loop. Then we did something unique, we attached an untreated canvas bag that can serve as a pre-filter for your water filter, as a tinder/foragers bag, or extra pocket to carry your water bottle or other tools while you're on the go.
