Leave the headlamp at home.

Four times brighter than a traditional headlamp, the UltrAspire Lumen 600 Waist Belt illuminates a broad swath of trail when you're hitting the trail long after sunset. The 600-lumen light features a focused center and wide-angle peripheral array, eliminating the "tunnel vision" effect of headlamps to avoid trip-causing obstacles in the dark. 180-degree rotation provides 90 degrees of adjustability up and down, allowing you to run up and downhill without sacrificing visibility.

Its robust aluminum housing is water, dust, and impact-resistant for years of trail running longevity. Breathable microfiber mesh keeps you comfortable when you're working up a sweat in warmer summer months. Dual-sided adjustment retains a secure fit for a wide range of users and will easily accommodate waists from 26 to 42 inches. Three lighting settings tailor the lighting to the conditions outside, with the light projecting a low, medium, high, and flashing S.O.S. beam for emergency situations.

Another cool feature is the Lumen 600's compatibility with the backside of UltrAspire's Synaptic hydration belt. This integration turns the Lumen 600 into a handy hydration belt on longer runs. Rounding things out, there's a large zippered pocket on the underside for carrying your running accessories. Also, it's USB compatible for quick and convenient recharging.

How to Measure:
For best results, take measurements over your underwear.

Measure the circumference around the point at which your body bends when you lean to a side (typically near your navel).
