Outdoor Research Swift Cap

Ultralight, Breathable UPF 40 Sun Protection for Trail Running and Beyond

The Outdoor Research Swift Cap is built for high-output days in the sun. Designed with a bluesign® approved recycled nylon blend, this lightweight performance cap delivers breathable comfort, water resistance, and UPF 40 sun protection for trail running, hiking, backpacking, and warm-weather adventures.

The shaped brim and protective nylon panels help shield your face and eyes from harsh sunlight, while the dark fabric under the brim reduces glare. Its low-profile design fits comfortably under helmets, making it a versatile option for alpine climbing, cycling, and ski touring. Weighing just 2.5 ounces, the Swift Cap is ideal for ounce-conscious backpackers and thru-hikers.

Mesh panels enhance airflow to keep you cool, and the moisture-wicking TransAction™ headband helps manage sweat during high-exertion activities. A quick-release back buckle allows for fast, on-the-go adjustments to achieve a secure and comfortable fit.
