When your ski pack's hydration bladder looks like a chemical concoction of everything you put in it for the past few years, get Dakine's Replacement Reservoir. Its low-profile Shape-Loc center baffle keeps the reservoir in shape until the last drop, and the removable hose allows for easy cleaning so you don't make the same mistake twice. Dakine set the high-flow bite valve at 45 degrees for easier drinking, and there are on/off positions for extra security. The reservoir's top opens wide for simple filling.
