The Oasis Crewe is the ultimate all-around base layer. It’s made from Icebreaker’s super-soft, 200gm merino jersey fabric, delivering warmth in cold conditions while breathing well as the body heats up. It’s merino wool construction wicks away cold sweat and resists unwanted odour build-up, making it perfect for repetitive use on weeklong excursions. This base layer also has offset shoulder seams to reduce rub when wearing a backpack, and flatlock stitching throughout that prevents chafing. The crew neckline helps give this Oasis a clean, wear-everywhere finish.
