Ever find your trusty Nalgene from college a little too sloppy on your outdoor adventures? Graduate from that old bottle to the Camelbak Water Bottle ($12). Featuring a unique bite-valve that contains no moving parts, you simply bite and sip. It holds around .75 liters of water, fits most cupholders, has a built-in handle that make it handy to attach to a clip or carabiner, is dishwasher safe, and — wait for it — is spill-proof, even when left in the open position. Excellent.
