The Upper Base Layer: Icebreaker Olympia and Slalom

New Zealand's sheep flocks (specifically, curly-horned merinos in the South Island's Southern Alps) have joined forces with wool-obsessed Icebreaker to bring you the season's best midweight base layers (Olympia for women, Slalom for men). And this merino's not your mother's wool: silky soft, breathable merino fiber insulates without soaking up your sweat, so you won't blow the après-ski crowd away with your stinky pits. Half-zips reach from the lower sternum to upper neck, thumb loops keep the sleeves from bunching, and the snug fit means absolute warmth and comfort regardless of your activity. $90; www.icebreaker.com
