CamelBak's Kids' Stainless-Steel Bottle has no inner liner or coating to ruin the taste of your child's drink. Its easy-sipping Big Bite Valve is simple, effective and won't spill if left open. An integrated handle makes it a cinch to carry the Bottle 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.
