This is a unisex PUMA DRYCELL cap with a detachable headlamp, making it easier to run or work at night. The PUMA cap features breathable DRYCELL technology with unique moisture-wicking properties (Photo 2), a reflective PUMA cat logo, a black color, adjustable size via Velcro (approx. 57-59cm), a 7cm brim, and is made of polyester. The underside of the brim has Velcro for attaching the headlamp (Photo 4). The headlamp uses 11 LEDs powered by three AAA batteries (Photo 5, on/off switch; the product includes only the cap and lamp, batteries are not included). The original lamp is secured to the cap's brim with long prongs, but Velcro has been attached to securely fix it to the underside of the cap's brim, making it easy to attach and detach. (The prongs have been removed, and there are traces of bending, Photo 6). The headlamp weighs 68g including batteries. I didn't feel the weight much while jogging, but some people might. The manufacturer is unknown. This product is a DIY combination of a commercially available cap and headlamp. It has been confirmed to light up properly and function without problems as a headlamp cap (Photo 7), but it is sold as-is. The cap, which has been used very little, is clean, but the lamp has been used. Both have some dirt and scratches from storage and use. This item is also listed on J○ti.
