Half Dome Helmet
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.

Great for the price and fits great
The helmet is pretty comfortable and I don’t get to hit wearing it one thing is it sits a little high on your head so it looks a little funny but I don’t really mind that but functionality it works great and mostly looks great

Pretty Goof
Get's the job done, not as comfortable as the petzl helmet I have, as in I have to tighten the dial a little more than I'd like for the helmet to feel secure. The chin strap is easy to adjust, and I like the dial in the back. Also, the pale blue color is really nice.

The classic essential
The half dome, when I think of climbing outside it’s paired with those crazy senders with no helmet and the even crazier senders with helmets. When you have a helmet you push harder and feel safer. The half dome is the perfect example of a balanced helmet. Light and sturdy. Comfortable and good looking. Paired with an affordable price, this classic helmet will be ready for whatever adventure you go to next. Highly recommend.

Fits well, is adjustable and good price/quality for an “entry level” helmet. There are definitely better, lighter, more breathable helmets out there but can’t really beat the price of the BD half dome.

A Great Helmet
I have taken this thing everywhere, I love the light weight feel that makes me feel protected nonetheless. Definitely doesn't have all the features that the higher end helmets have but the boa in the back tightens to my head just fine, it has enough ventilation for me to hike with it on when doing scrambles and I take it climbing all the time.

Great overall helmet
Not the most light weight and has a few snag points but it just depends on what type of climbing you’re doing

Great helmet for the cost
- Familiarity:
- I've used it once or twice and have initial impressions
Used this helmet to hike Black Tusk in British Columbia. The fit was good. Chin strap was a little annoying, but that is any helmet.
