The Crux reservoir on/off valve pairs with our Big Bite valve and tune. Using an integrated valve, water flow shuts off for added security during transport.

• "45 degree angle eased drinking and improves water flow. Pair with the new Crux tube for 20% more water flow per sip.
• Works with all Camelbak Crux reservoirs but not compatible with Camelbak Antidote and Omega reservoirs
• Bite valve and tube sold separately"
