    Hopefully you'll start climbing Half Dome around sunrise, because if you don't you'll definitely finish climbing after sunset. Either way, the Black Diamond Half Dome Helmet has headlamp clips as well as safety features. This helmet is Black Diamond's original, updated for more ventilation and a lower weight.

    • Co-molded foam with low-profile, lightweight polycarbonate shell

    Great helmet NOT for challenge course

    • Familiarity: I've used it several times

    Purchased the Half Dome helmet for our university hybrid indoor adventure climbing class because we liked the weight, the mechanism for tightening and the straps. We thought we had a real winner until we were inspected by ACCT and they would not certify our new helmets. The Black Diamond Half Dome are to be used in mountaineering, rock climbing or ice climbing, but not for use in challenge courses such as ours. The nice folks at Black Diamond were helpful, but unable to assist because they don't make helmets for challenge course use. Unfortunately Backcountry doesn't put the "fine print" on their website, so I didn't know that these helmets were not for challenge course use. We got a good deal on the purchase, but are now disappointed that we have to buy more helmets that meet the standards for ACCT. Read the fine print "instructions" on Black Diamond's website.

    Black Diamond Half Dome

    • Familiarity: I've put it through the wringer

    Not my personal helmet, but I’ve worn one 5 days a week all summer for my work and have certainly had time to familiarize myself. A few rocks to the head and two less than graceful falls later I can certainly say my brain is all
    The better for it. Comfortable (as far as helmets go) and durable, thanks to the hard outer shell. An excellent introductory or workhorse helmet for those who don’t want to see every dent in their fancy $150 foam domes.

    So far, so good.

    • Familiarity: I've used it several times

    I bought the Half Dome for my first helmet because it had good reviews and the price wasn't outrageous.
    I've had it out doing some sport climbing and recently on my very first multi-pitch. It's easy to adjust and pretty comfortable. I haven't taken any huge whippers with it yet, nor been subjected to falling rock, but at least I know I'm doing my best to protect the old noggin.

    Second Time Around

    • Familiarity: I've put it through the wringer

    After retiring my first half dome, I was happy enough to buy another. I don’t feel the need to spend $100+ on a helmet and this does the job and is lighter on your wallet.

    Classic Helmet

    • Familiarity: I've used it once or twice and have initial impressions

    The BD Half Dome is a classic climbing helmet. Good for everything from sport climbing to big walls. Super durable and functional, this helmet will last for years and years.

    Great Climbing Helmet!

    • Familiarity: I've put it through the wringer

    This is a quality climbing helmet. It comes in more handy for saving your dome from swinging cams when you carelessly whip your gear sling over your shoulder, but this helmet will also protect you from serious damage should you take a serious whipper or be subjected to falling rocks and ice. This helmet is adjustable, but it can get mildly uncomfortable when worn for several hours on end. Overall, lightweight, breathable, versatile, and full of peace-of-mind.

    Great Climbing Helmet!
