OPST heard many calls for the return of the roll-top waist pack, and they have answered them. Their sturdy waist/sling pack has a roll top, avoiding the inevitable leakage that occurs with zippers. The side straps are adjustable so you can choose how tightly the bag is closed and make sure the 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.
