The Nitecore NU25's ultralight weight, features, and form factor have made it a staple in the outdoor community for years. It features multiple brightness levels, simple controls with separate buttons for red versus white light, and a built in rechargeable lithium ion battery. The NU25 is one of the most versatile and compact headlamps available.

We've taken this feature-rich headlamp and included our custom-made Zpacks Pro Headlight Headband; providing added comfort at a weight savings of a half of an ounce compared to the stock headband (also included).

Reinvention of something already better

Sorry litesmith beat you to this by years with a lighter, easier to see, and better adjustment option. Come up with something new!



Hello David, We used similar hacks ourselves and found that while it was functional it wasn't very comfortable. While we enjoying being masochists in our efforts to save weight, in this particular application we focused on achieving a low weight while maintaining comfort as the juice simply wasn't worth the squeeze for the minimal extra weight savings.
