Dump the inner tube! This lightweight, compact, made in the USA number is billed as a "freestyle mini luge." Unlike regular sleds, this one allows for simple steering and vertical racing down steep terrain. Offered in a variety of candy colors like pink, red, and lime, there's a luge to suit every taste and personality. And because it's so light, kids can easily carry it back up the hill. If you've ever longed to try luge after watching the Olympics, Zipfy gets you that exhilaration, minus the gold medal. (Zipfy, $39.95)
