The Icebreaker Mens Tech Top Longsleeve Crewe thermal top 2020 has a new and improved cut and fit because we have your comfort in mind! The tail is dropped slightly for better coverage, and the underarms are gusseted for much better range of motion. This top is perfect, whether you're carving the slopes on your favorite local mountain or trekking across a high Sierra glacier. This long sleeve merino shirt is soft next to the skin, breathable, and warm. Something thoughtfully designed with carefully-placed seams to avoid chafing, that also stays fresh while you're traveling. In regular fit, and 260 Midweight. Made from 100% Merino Wool, which is warm, highly breathable, and odour-resistant.
