Soft and simple underwear that offers minimalist comfort, the Siren Thong features icebreaker's corespun fabric that’s incredibly durable and soft next to your skin. The forward side seams and bulk-free design make for simple, chafe-free comfort during both active and daily wear.
Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics. Merino is an annually renewable fiber that naturally resists odors, keeps you cool when it’s hot and warm when it’s not, and lets your skin breathe for comfort all day, every day.
