How To Give Him The Best Gift He'll Ever Receive

Cool Gear

"I love to go backpacking, so my girlfriend often gets me cool gear. I love it when she finds the things I've never even heard of." Aaron, 25, California

Affordable: The durable, portable Pisat K-Light is a great tool, whether he's off in the wilderness or trying to conserve energy at home. It's so small and light (about the weight of a can of soda) that he'll be surprised by the amount of bright, sun-powered light it gives off. ($49.95, what-if.com)

All-Out: The Celestron SkyScout Personal Planetarium (pictured) uses GPS technology, gravity and directional sensors to discern constellations without the hassle of complicated sky maps. With a point and click mechanism, it's easy to identify more than 6,000 stars, all 88 constellations, and more than 100 deep space objects. It can track and inform him about celestial events that may be in store on a given evening, and if nothing's happening it'll still keep him entertained with informative audio and text information. It's lightweight and rugged, so he can cart it to the farthest reaches of his adventures. ($199, rei.com.
