The Patrol I pack features a unique "interlocking pocket system" that allows you to carry more medical gear, with more comfort and security than with flat aid belts. The Patrol I's main pocket opens with huge #10 coil zippers, has four internal dividers, and four elastic keepers. Its outside bellows pocket expands to carry quickly needed items. Taped seams, Ripstop para-pack cloth construction and highly contoured suspension with a double adjust buckle make this the most comfortable and usable aid belt in its price range.
