An elevated, sportier version of icebreaker's best-selling base layer, the 200 Oasis+ Long Sleeve Crewe is a versatile top that make the perfect foundation for your everyday year-round layering system. Made with 100% merino wool jersey fabric that’s breathable, insulating, and naturally odour-resistant, the Oasis+ features a slim fit, raglan sleeves and a gusseted construction designed for increased mobility. Flatlock seams throughout help reduce friction. 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.
