CamelBak's Stainless-Steel Eddy Bottle has no inner liner or coating to ruin the taste of your drink. With a double-wall, insulated, stainless-steel construction, it keeps your drink warm or cold, and is incredibly durable. Its easy-sipping Big Bite Valve and straw are 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.
