OPST heard the call for the return of the waterproof roll-top waist pack, and we have answered you. Our sturdy waist/sling pack has a roll-top, avoiding the inevitable leakage that occurs with zippered waterproof packs. The side straps are adjustable so you can choose how tightly the bag is closed and make sure water stays out. The waist is fully adjustable and features a UTX buckle for added durability. A padded insert keeps your tools and boxes organized and also protects the bag from the inside. The front zippered pocket has drain holes to keep your tools and tippet from soaking for long periods. The pack can be worn with or without the removable sling, making it a perfect crossover hip pack/sling pack.
