PETZL Unisex's E104BA00 Bike Part, One, Size

Lightweight, ergonomic rechargeable headlamp with AIRFIT headband. Provides 500 lumens of brightness at only 79 g. Ergonomic and comfortable AIRFIT headband: innovative, streamlined design, with semi-rigid headband and ultra-thin lamp body. Battery pack in the rear to distribute headlamp weight over the entire head, making it balanced and comfortable enough to be almost imperceptible. This water-repellent headband resists sweat and rain. Optimal visual comfort, with LED configuration that distributes light homogeneously. Two beam types (flood or mixed) and many white brightness levels to meet different needs: proximity lighting, movement, and distance vision. Headlamp charges via micro USB port. HYBRID CONCEPT design: the lamp comes with the Petzl CORE rechargeable battery and also works with three AAA/LR03 batteries (not included). Storage pouch allows it to be transformed into a lantern. Can fold flat in its pouch to reduce bulk. Reflective components on the back of the lamp, making the user visible at night. Two LOCK functions prevent the lamp from turning on during transit or storage. Compatible with all Petzl helmets.
