The NU21 lightweight rechargeable headlamp is an ideal choice for both runners and outdoorsmen. Its unibody optical lens system is specifically designed to emit a uniform and soft light, capable of reaching a maximum brightness of 360 lumens, with a range of up to 63 yards. This makes it particularly suitable for night running and route finding. The NU21 offers versatility with four brightness modes, as well as emergency SOS and beacon functions. Additionally, it can switch to dual red LEDs, preserving your night vision or serving as a long-lasting signal light. Weighing just 1.55 oz, the NU21 is constructed with lightweight and durable materials. Furthermore, the reflective headband glows in the dark, enhancing your safety at night. With its hollow bracket design and ultra-lightweight headband, the NU21 offers a weightless feel, making it perfect for trail running, jogging, backpacking, and trekking.

The NU21 headlamp offers convenient USB-C rechargeability and boasts an impressive maximum runtime of 37 hours on its lowest setting. With its integrated USB-C port, the NU21 can be fully charged in just one and a half hours, ensuring minimal downtime. A power indicator keeps you informed about the battery status, while the lockout mode prevents accidental activation. The headlamp's ultra-low standby power consumption guarantees a ready-to-use experience for 365 days, and its highly efficient constant current circuit ensures a comfortable visual experience. The intuitive dual-button interface places the controls within easy reach, allowing you to focus on your surroundings and enjoy your activities. For added durability, the NU21 is rated IP66 water resistant and can withstand impacts of up to 1 meter. With its three stylish colors, the NU21 offers a splash of style for your gear.

We can ship to virtually any address in the world, and we offer same-day shipment of most orders received before 11am PST. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.

When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.

Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.

Returns Policy

You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
