Rated 4.6 out of 5 by 8 reviewers.
Rated 4 out of 5 by Excellent product I use these with my scouts. They are more comfortable than other brands because of the adjustable rear strap June 23, 2014
Rated 5 out of 5 by Good value Great fit, lightweight, durable and affordable. I would definitely recommend this helmet to any level of climber June 10, 2014
Rated 5 out of 5 by Excellent I am pleased, as a guide, to say that I love these helmets. The jury is out on durability over time, but. . .the fitting is EASY for my clients to figure out. I also like the colors. They make climbing much safer out here in West Virginia because the brightness tell hunters that we are not game. May 2, 2014
Rated 4 out of 5 by Tried and True Ahhh the Half Dome helmet. What can you say? I think I have three of them. They perform like a helmet should and have saved my dome from it's fair share of falling ice. It fits well and keeps my head warm on chilly ice routes. The only downside it the rear retention straps are hard to pack away, but that has been addressed on their new models. A great inexpensive trustworthy helmet. November 12, 2013
Rated 5 out of 5 by Wife and I Both Love It We both own and appreciate this helmet. I wear mine all day at Smith Rock, OR even when it's in the 90s (for sun protection on my balding head). The helmet is comfortable and breathes relatively well. October 10, 2013
Rated 5 out of 5 by Light duty workhorse The Half Dome is light and comfortable, so I don't mind wearing it. I don't really notice it is there, sort of like a seatbelt. As a foam-lined helmet, it will not take abuse quite like a full-suspension helmet, so I use a full-suspension style helmet for days when I _expect_ to take lots of scrapes & hits. Otherwise, the Half Dome protects my head on the days I would have otherwise gone bare-headed, because I don't mind wearing it. "The best kind of helmet is the helmet you will wear" October 3, 2013
Rated 5 out of 5 by great price, great product I have a huge head and love the dial adjuster. Wore it all day rappelling and climbing, almost forgot it was there. Friend has same helmet with same results: fits well, comfortable. You can't beat this helmet for the price. September 14, 2013
Rated 4 out of 5 by Works if you use it! Baseline model, but plenty of safety features to keep your noggin happy. Very adjustable to fit all sizes and shapes of heads. Interested to see the new version - as mine is a couple of years old by now. May 17, 2013
