Smartwool Women's Classic Thermal Merino Wool Base Layer Crew (Slim Fit), Marmalade Heather, Large

VERSATILE MID-LAYER. Made with a responsibly sourced Merino wool/polyester blend, our Men's Merino Sport Hoodie is designed for those times when you might break a sweat even when it's cool—did someone say a fall hike or early spring mountain bike ride? REGULAR FIT.

Designed to meet the demands of outdoor adventuring, this regular fit base layer offers room to move throughout the silhouette without any additional bulk. ACTIVE MERINO. Made for warm to cool weather, this ultra lightweight hybrid fabric features engineered mesh in key areas to aid with breathability, Merino next to skin for temperature regulation and polyester for durability and faster dry times.

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 — flatlock seams help to dramatically reduce chaffing, keeping you moving comfortably.
