4 SEASON BASE LAYER. Designed for extended durability, this Merino wool long sleeve is exactly what you need to keep temperate all year round. Molding to the contours of the body, this base layer adds a fine line of comfort for all day use.
SLIM FIT. Designed to meet the demands of outdoor adventuring, this slim fit base layer shows off a slimming silhouette while offering unrestricted movement through the arms and chest.
CLASSIC ALL-SEASON MERINO. Perfect for 4 season layering and everyday comfort, this ultra lightweight performance fabric blends Core Spun Tech that maximizes durability with the thermoregulation and moisture wicking power of Merino wool.
WHY MERINO WOOL? Thinner and softer than regular wool, it's easy to wear next to skin. Each fiber transports sweat away as a vapor (we tested it ourselves) and regulates body temperature to keep you cool in summer and warm in winter.
FUNCTIONAL FEATURES. Go far, feel good with thoughtful tech to keep you trekking comfortably — offset shoulders and flatlock seams increase comfort and minimize chaffing, while the seams also wrap to the front for a body-enhancing fit.
Description
In any season or sport, when we need added warmth, we start our layering system with the Smartwool Classic All-Season Merino Base Layer. Overnight summer backpacking trips, shoulder season hikes, and active skintrack ascents keep us on our feet year-round, and merino wool helps us combat the chill without letting us overheat or weighing us down.
