Outdoor Research Swift Cap

Ultralight, Breathable Sun Protection for High-Output Days

The Outdoor Research Swift Cap is a lightweight, breathable performance cap designed for trail running, hiking, and fast-moving days in the sun.

Built with a bluesign® approved recycled nylon blend, it delivers UPF 40 sun protection, excellent breathability, and quick-drying comfort in warm conditions. Mesh side panels maximise airflow, while the moisture-wicking TransAction™ headband keeps sweat off your face when the pace picks up.

A shaped, stiff brim provides reliable sun protection, with a dark underbrim to reduce glare. The low-profile design fits comfortably under a helmet-making it ideal not just for running and hiking, but also for alpine climbing and ski touring.

Lightweight, packable, and easy to adjust on the move, the Swift Cap is a go-to essential for any warm-weather mission.
