Half Dome Helmet

Protect your melon on your next climbing trip with the comfortable, adjustable, low-profile Black Diamond Half Dome Helmet. Whether you just shaved your head before a trip to the desert or you're wearing the thickest stocking hat you own, this helmet perfectly fits your head thanks to a one-hand adjustment knob. A simple twist makes the Half Dome Helmet's circumference bigger or smaller to match your headwear or hair style. Its low-profile design keeps the dork factor down when you're at the crags, and may save you from getting your head stuck in an offwidth one day.
