Climbs, ski tours, trail runs, surf trips – the Sima frees you to follow the sun. Made from Diem™, a 100% recycled polyester made with wicking fibres, it stretches for freedom, allows cooling airflow, and feels great. The low-profile hood protects the head and fits under a helmet. It’s patterned for freedom of movement and has a streamlined fit that allows it to be worn as the base of a layering system.
