Go big. The largest of our ultra-light series, the UltraFlask Speed 600 ml holds more so you can go the distance.

Replacing your bite valve from time to time helps maintain your hydration system. HydraPak's Bite Valve Sheaths provide a soft bite and are made of durable silicone. Perfect for chewers or to keep in your emergency gear kit with your bandaids and duct tape. Fits and replaces all HydraPak bite valves on our Reservoirs, SoftFlasks, and UltraFlasks.  *Please note - Blaster Sheaths DO NOT fit on the new Comet Bite valves and are not compatible with any of the new 2023 reservoirs.

When it comes to hydrating equipment, heavy duty use needs heavy duty cleaning. Bottle Bright tablets are readily biodegradable, safe & environmentally friendly, made to keep all your containers clean and operating at optimum performance. Contains 12 tablets. Use one tablet per liter of water.
