The workhorse Black Diamond Half Dome helmet is designed to take on all your mountain pursuits, from cragging to alpine expeditions.

  • Features

    • More than 40g lighter than its original version, Half Dome is still the most durable helmet that Black Diamond offers
    • Hybrid design uses molded EPS foam inside and a hard plastic shell outside to protect your head from impacts
    • Large vents on the sides and back help keep your head cool on hot summer days
    • Internal headband adjusts with a nape-mounted dial so you can fine-tune the fit; dial is easily operated with one hand
    • Low-profile clips keep your headlamp (sold separately) secure, even when you're climbing in tight spaces


    To find your size, position a tape measure just above your ears and about 1" above your eyebrows. Keep the tape level to measure the circumference around the largest part of your head and then find the corresponding size in the Technical specs info.
