Has already saved the noggin quite a few times! *by on Reviewed in the United States May 3, 2016* I purchased this helmet for outdoor climbing. My favorite parts about this helmet when originally purchasing were:- The cheap price point compared to other helmets of the same quality- The stylish design when compared to other helmets in the same price range- The very light weight profile- The ability to hold your helmet light up- The ability to save my head from disasterAfter having purchased and used the helmet a few times, I would say that one of my favorite things about it is definitely the light profile. I have found that I forget that I'm even wearing the helmet sometimes! It is very comfortable and the ability for it to fit most sizes of heads is also pretty wonderful.Be cautious when looking into sizing. My girlfriend was purchasing the purple version of this helmet and believed she would be a small. When actually trying on the small at a local REI, we were really glad we checked it out first. The small is definitely for the head of a child! Medium is likely applicable for most people who don't have a very small or very large head!I honestly have no cons that I can come up with for this helmet as of yet. For the quality and price, and a name brand like Black Diamond, you really can't go wrong with this! Get out there and climb some rocks! ### ⭐⭐⭐⭐⭐ my helmet isn’t just part of my gear — it’s my lifeline *by on Reviewed in the United States August 12, 2025* 10/10 – Tough, Lightweight, and Cave-ProofI’m a spelunking guide and use this helmet for hours every week underground. It’s lightweight, comfortable, and fits securely even during climbs and tight crawls. After months of scraping against sharp rock, it’s still in great shape. If it can survive caving, it can handle anything. ### ⭐⭐⭐⭐⭐ Great *by on Reviewed in the United States July 14, 2026* Great helmet fits well works well ## Frequently Bought Together - BLACK DIAMOND Half Dome Helmet (New 2019) - BLACK DIAMOND Men's Momentum Rock Climbing Harness - BLACK DIAMOND 9.9 mm Dynamic Rock Climbing Rope --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/176053629-half-dome-rock-climbing-helmet-adjustable-fit-ventilated](https://www.desertcart.nz/products/176053629-half-dome-rock-climbing-helmet-adjustable-fit-ventilated) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-09-29*
