The Bobble water bottle is the best of both worlds: a self-filtering bottle that looks pretty darn cool.

This 34-ounce bottle is BPA-free and constructed from recycled polyester -- so it's also completely recyclable if you ever need to upgrade. The carbon filters last for two months or 40 gallons, and though the company doesn't recommend using them in places where the water is "microbiologically unsafe," they'll make the tap water at your favorite campsite a whole lot more palatable. (Bobble Water Bottle, $9-$13)
