Kite Patch
For most of us, mosquitos are nothing more than a nuisance we have to tolerate when we spend time outdoors — for the rest, a mosquito bite can mean illness, or even death. The Kite Patch ($35) renders people virtually invisible to mosquitos, without the harmful, nasty chemicals found in many of the solutions we use today. These small stickers adhere to your clothing, disrupting mosquitos' ability to detect the carbon dioxide we exhale. Even better, when you buy ten Kites, they'll send ten more to a family in Uganda, where mosquito-born illnesses are more severe than anywhere else in the world.
