Master sun protection and airflow in this highly technical yet lightweight jacket. Constructed from a 20D ripstop nylon with a UPF 50+ rating, it blocks over 98% of harmful UV rays while offering durable, packable protection. A DWR finish sheds light rain, and the fabric's crinkled texture enhances tear resistance. The standout feature is its comprehensive ventilation system, with full-length underarm YKK zippers and a chest zip for maximum airflow control during high-exertion activities. Designed for an active fit, it includes a structured hood with a TPU-brimmed visor, a ponytail-compatible rear adjustment, and thumbhole cuffs for extended coverage. Practical elements like a self-stowing pocket, multiple zip pockets, and an adjustable hem round out this versatile layer for running, fast hiking, and cycling in variable conditions.
