Rated 4.5 out of 5 by 19 reviewers.
Rated 4 out of 5 by gets the job done If you're climbing or belaying (outside of the gym) you should be wearing a helmet. This one is durable enough to last you years of service, and is priced to be entry level. No, its not ultra-lightweight, but it has a one-handed adjustable backstrap, and doesn't actually look half bad. Note: when you first get it, adjust the sizing of the straps, including moving the chin strap forward if you need to (you can feed strap from one side to the other via the back of the helmet). This prevents the feeling of being choked by the chin strap, which shouldn't happen if it's properly adjusted. March 17, 2015
Rated 5 out of 5 by Excellent Brain Bucket If fits close, doesn't weigh much, easily adjustable and looks like it will be cool in summer. For winter I have an old military helmet beanie to wear under it. It's a huge improvement over the old MSR helmet I used to use. But it will be too strange looking to use for skiing.

Rated 5 out of 5 by Simple and Effective I don't climb as often as I would like. I needed a helmet that kept me protected, but realistically I expect to retire a helmet once it takes a good hit. For me, I did't see the advantage of going with a more expensive helmet. I'm very satisfied with the fit and feel of the half dome! February 19, 2015
Rated 1 out of 5 by The headband is uncomfortable The rectangles of hard foam on the front of the headband make my Half Dome unwearable. If it's adjusted tight enough to prevent wobbling, it rubs and leaves red marks on my forehead. February 17, 2015
Rated 5 out of 5 by Great Fit I ordered this helmet because it is required for search and rescue. I was surprised by how easy it is to adjust. I had adjusted it to fit directly on my head, but when I got to the training center it was horrible weather with a rain/snow mixture. I was able to quickly adjust the straps to fit over my warm hat and it was comfortable to wear all day. January 19, 2015
Rated 5 out of 5 by Comfortable, lightweight, durable Just an all-around great helmet for the reasons listed above. My hat size is 7 1/2 inches and the M/L fits me perfectly. December 9, 2014
Rated 5 out of 5 by A true work horse I bought this only after switching to those the fancy light weight super-duper helmets. I sat on my fancy one and broke it. So now the light weight foam helmet is saved for when I am really weight conscious, but this is what I use and abuse (although I don't really abuse it). Durable and almost equally light and as comfortable as any other helmet. If you are going to own one helmet, make it this one. November 14, 2014
Rated 5 out of 5 by Perfect for zip lining and GoPro in Costa Rica! Fits very well, adjustable for correct fit under chin. If your head size is right in between SM/ML, go with the bigger helmet for sure. My new wife and I each got one for mounting our GoPro hero 4 black and Cat Eye Volt 300. Perfect set up if you ask me. Very pleased Ps, one slight improvement I'd make (but helmet is great as is) is a thin padded cover over the bottom of the chin strap. With added mouts and weight, strap can cut into me a bit. Offering and optional add on would be awesome. Thank you, helmet is 9/10 and customer service while returning my sm for a ml size went easy as possible, and quick! ... G&A Duoos November 8, 2014
