Fuel Belt

If you're a regular runner or hiker staying active in this summer heat (come on, just play some Xbox already!), then you need to grab yourself a Fuel Belt to help keep hydrated. The Endurance 4-Bottle Belt ($34) lets you easily take along four bottles filled with your favorite liquid in a comfortable stretch belt with velcro closure. It also has reflective material for low light conditions and rear pocket to hold your keys, ID and credit card.
