Helm of Sun Valley

Over the course of 50 years, the family that runs Helm of Sun Valley has amassed an inventory of top-shelf gear for wintry recreation and summertime watersports. Before stocking their shelves, the shop's athletic staffers take skis from Alpina, kiteboards from Cabrinha, and water skis from Connelly for test spins to appraise their performance. Standout sports gear snags a spot inside the store, along with apparel and accessories. Employees also rent out and tune up equipment. They specialize in fitting snowboard boots to feet, sometimes fashioning custom ZipFit liners by molding foam around arches. New kiteboard owners can master the sport by attending lessons, during which instructors teach basics on land before waving pupils onward into frothy crests.
