Bringing together multiple technologies! The IKO® CORE rechargeable headlamp combines multiple technologies to provide 500 lumens at a total weight of only 79 g. Featuring an AIRFIT®, headb&, an ultra-thin lamp body, & an energy source worn in the rear, the headlamp is balanced & comfortable enough to be imperceptible. It’s versatile & can also be worn around the neck or transformed into a lantern using the storage pouch. It can fold flat to reduce bulk, making it practical for all outdoor activities. With its HYBRID CONCEPT design, IKO® CORE comes with the CORE rechargeable battery but also works with three AAA/LR03 batteries (not included).
