Ski tour La Vallee Blanche with the R3 Radiant zipped into our Liquid Sky Jacket (p. 15), then ditch the shell for cozy power-lounging back in Chamonix. The Radiant grants serious insulation, and has zippered handwarmer pockets and an internal stash pocket. Now with a cleaner fit in the arms and torso. The women's jacket has a trim, sculpted cut.
