Love the crisp, clean taste of filtered water, but don't have a way to take it with you? Pick up CamelBak's Groove Insulated Bottle! An integrated filter turns 20 ounces of everyday tap water into great-tasting refreshment on the go—and keeps it cool! The Groove's easy-sipping Big Bite Valve is simple, effective, and won't spill if left open. An integrated handle makes it a cinch to carry with a finger or clip it to a carabiner. Plus, the Bite Valve flips down flush with the bottle to keep it clean. And of course, like all of CamelBak's bottles, it's 100% BPA free.
