A double-wall construction keeps water cold for twice as long as regular sport bottles in the CamelBak Podium Big Chill 25 oz. hydration bottle. The innovative, self-sealing Jet Valve™ will ensure that your hydration ends up where you need it and not spilling out all over your gear. When you’re on the move, the lightweight, easy-squeeze design is incredibly easy to use. The bottle features cool graphics and large CamelBak wordmarks all the way around.
