Petzl Swift LT

This is a truly lightweight headlamp—just 43 grams—and small enough to disappear in your pocket or the bottom of your pack. It puts out 380 lumens, which is enough for cross country skiing on dark winter evenings, cooking after dark in your campsite, or trail running at night.

The headlamp has three white light settings, plus a red light for preserving night vision and not blinding your partners. The minimalist headband is comfortable and low-profile, with a reflective thread woven in for added visibility. The battery is USB-C rechargeable (charging cord not included).
