Arcteryx Sima Jacket Mallow UPF 50+ W’s

Summer’s sun invites us to hike. It brings blue skies, longer days – and the realities of heat and damaging rays. The Sima is your shield. Ultralight, easily packed, and exceptionally breathable, it stays cool on hot days while delivering UPF 50+ protection. 100% recycled Diem™ stretch polyester dries fast and feels soft on your skin. A gill vent at the back increases airflow, the tall collar extends protection, and the jacket stuffs into its side pocket for easy transport.
