The sun beats down. The Sima protects. On the trail, snow, water, and rock, this ultralight, soft, technical hoody delivers UPF 50+ protection. 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.
