CamelBak's HydroLink Filter Adapter enables you to refill your reservoir through the drinking tube. Attach the HydroLink between the hose and your water filter (sold separately) and you are ready to replenish your water supply.
CamelBak's Ergo HydroLock controls your fluid flow with the flip of a switch. Turn it on to drink, turn it off for added security during transport. Simply insert it into the end of your CamelBak drinking tube and attach the valve to the other end. Plus, the 90-degree bend makes sipping on the go a cinch!
