An incredibly warm Merino wool base layer for the coldest months of the year, the 260 Tech Long Sleeve Crew is a go-to piece for winter layering, ideal for skiing, snowshoeing and other cold-weather pursuits. Featuring an odour-resistant, 100% Merino wool jersey fabric for premium softness, insulation and breathability, the 260 Tech is a warmer version of Icebreaker's best-selling Oasis top. The gusseted underarms allow for ample range of motion, while flatlock stitching and offset seams throughout make for a soft next-to-skin feel. Inspired by nature, Icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics. Merino wool is an annually renewable fibre that naturally resists odours, keeps you cool when it's hot and warm when it's not, and lets your skin breathe for comfort all day, every day.
