An incredibly warm merino base layer for the coldest months of the year, the 260 Tech Long Sleeve Crewe 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. The gusseted underarms allows for ample range of motion, while flatlock stitching and offset seams throughout makes 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 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.
