The Longboard Outdoors Beanie - 5 Bright Integrated White LEDs - Batteries Included - Hands Free Winter Hat with Headlamp for Running, Hiking, and Walking Without Needing a Flashlight. BRIGHT WHITE LEDs - No more carrying around a separate, heavy headlamp or flashlight now. The 5 white LEDs are integrated and make a great headlight to find your way. Warmth and bright light in one! LIGHTWEIGHT - at only 2.5oz, it's perfectly comfortable when hiking, running and jogging. Forget that pain in the neck headlamp and its heavy battery pack. This baby is super lightweight and you'll wear it for hours without even noticing. BATTERIES INCLUDED - Two CR2032 type coin cell batteries included. You'll get about 24 hours of continuous use out of the LEDs. The batteries are simple to replace inside the brim of the hat. WARM - 100% acrylic that will keep your head warm and dry. Don't worry, the lights don't add any heat to your noggin while in use. This is the perfect combination of warmth and visibility! SIMPLE TO USE - The On and Off switch is located under the brim of the cap. You can see it in the pictures. It's easy to use and operate. After a couple times of feeling for the switch, I have faith that you'll get the hang of it and can even operate it with gloves on.
