    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!
