When negative temperatures or cold hands threaten to send you packing on a perfectly good ski day, the Black Diamond Solano gloves deploy supplemental battery-powered heat to keep you going lap after lap. On the exterior of the gloves, a premium goat leather shell backed up by a fully waterproof and breathable GORE-TEX insert stands up to the rigors of long days on the mountain in variable conditions. Inside, low-profile and fully rechargeable AddHeat Technology provides three-level warmth thatÂs controllable via an integrated LED switch. PrimaLoft Gold insulation and a fleece palm lining offer ample warmth on milder days. A zippered carrying case and included outlet adapters make for easy storage and charging while traveling.
