The Chute .6L offers hydration on demand with bright new colors and a leak-proof design that's small enough to toss in a bag. The leak-proof, tethered cap twists off with just half a turn and conveniently snaps into the handle so it's out of the way when you're drinking. CamelBak even put the threads for the cap on the inside of the spout so you get a comfortable lip seal. And the one-piece tether is twice as clever as any you'll see on the market. It keeps the top locked out of your way for one-handed refills on the go.
