CamelBak’s Delta-5 Tactical Vest and ST-5 Tactical Pack integrate the company’s FDA-registered HydroGuard technology, which eliminates up to 99.99-percent of common bacteria and fungus on reservoir and tube surfaces to keep water clean and taste free. The vest and pack include an internally routed, high-flowing drinking tube that can be routed over either shoulder, while CamelBak’s Big Bite Valve provides easy water flow and a cover to keep it clean when not in use.
