What's loved by some, might not be so loved by others. So instead of compromising, we at Knog have made 10 x designs for three lights. Some are mild. Some are wild! But the striking form does not outshine the excellent function. Super bright, AA battery-powered, long runtimes, replaceable straps, and side illumination. So whoever you are, find your POP!
