BEST FOR POWDER

Typically, a 118mm underfoot ski would feel too heavy to take out of bounds. But by fusing together fir, aspen, and maple, K2 made the SideSeth's core nearly 5 percent lighter than the competition's. It floats in powder and dances through glades, but the best part? The lack of metal doesn't hinder performance: It's still burly enough to bomb large turns in spring crud. [$800; k2skis.com]
