This durable accessory pouch from Blackhawk is designed to fit a Mark 4 canister, as used for pepper and CS sprays and other chemical agents. It is made from rugged Cordura nylon for strength and wear-resistance, and features a polymer insert that provides additional protection against impacts to prevent denting. Inside, a smooth liner minimizes wear on the canister surface to preserve its markings, and a soft foam spacer allows it to easily accommodate sprays with extra-large nozzles. Its top flap folds over to provide full coverage and fastens with a reliable quick-release snap.
