The "Better Bottle" just got even better.  The Camelbak Eddy combines a durable BPA free bottle with the convenience of a bite valve.  The bite valve design means no sloshing or spilling.  You don't even have to tip the bottle up so there's no obstruction when getting a drink while riding driving or walking.  The redesigned lid and straw combination also offers greater durability and improved water flow.  The whole package is guaranteed for life with Camelbak's "Got your Bak" guarantee.
