Powerful lumens and rich features in an ultra-compact space. BioLite’s breakthrough 3D SlimFit technology integrates headlamp electronics directly into the performance fabric band for a true wearable. No bounce, no slip. A little push on the back gives you 30 seconds of MAX brightness on the front. Heads up: it’s real bright. As a rechargeable headlamp, you can extend Headlamp 750 runtimes indefinitely thanks to pass-thru charging. This means you can use your headlamp while simultaneously powering it up.
