The Merino 150 Siren Bikini is stretchy and soft next to your skin, a slim-fit underwear for go-to everyday comfort. The Siren's light 150gm Merino Corespun fabric helps regulates body temperature in all weather conditions. The low-profile style features a modern, bulk-free fit with optimal coverage, and the forward-set side seams eliminate chafing. 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.
