"Solid helmet choice. I find it more comfortable than some other models at BD. Been using it at the crag and in some southern Utah canyons. The headlamp holder is super convenient, it stays put well and protects the noggin. What else do you need?"
"Replacement for my old half dome that saved my life from icefall on Mount Hood."
"Great product as anticipated. The helmet fits perfectly and the adjustable strap keeps the hemet snuggly in place. Headlamps stay where they should due to the clips. The helmet is lightweight and comfortable, perfect for working in a cave environment!"
"I like the fit! Solid buy!"
"My BD headlamp integrates perfectly with this comfortable and lightweight helmet. No thrills, but it protects my noggin."
"Compact and comfortable with nice head lamp clips"
"This helmet has been great for me. Have climbed several days in it, and it's super comfy and fits my head great. I had an old-gen half dome before this, and the new one is even better."
"I bought this for my brother as a Christmas gift. After asking him to measure his head, it turns out that his head was the cutoff between sizes in inches. He measured again in centimeters and was sized as a S/M. When he tried it on at Christmas it looked to barely fit. I would recommend to the next person who is between sizes to get the M/L. Less headaches and room for a beanie"
"Fortunatley havent taken a big impact to this, which would be its practical test, but its stood up to scrapes just fine and was a good, affordable helment."
"It fits very precisely to the head measurement. Eg. If you measure 23” then size up so you can put a beanie or hood under it."
