A climbing helmet needs to do two things: protect your head and be reasonably comfortable. The Black Diamond Half Dome does both well. It's durable, well ventilated, and the fit system make sure I can put it on and go climbing without thinking about it.

great for rock climbing and mountaineering
I use this helmet for Utah canyoneering. I wear it all day, sometimes over a billed hat to keep the sun off and sometimes without. It's comfortable and easily adjustable to varying head sizes. The adjustment knob is simple and I like it better than the Petzl Elios adjustment. Overall I prefer this helmet to the Elios. The value can't be beat. Especially when on-sale.
Use Situation: Canyoneering
Picked this one as a result of my Mastiff eating my others, read some reviews of this and tried it on at my Local store, got a better deal from Whittaker. I like the rear lock-nut to increase or decrease size, well ventilated and Light for me. I tried on a few, Mammut, Grivel,Petzl... this fit the best and was the coolest for me. I honestly felt more secure in this... for some odd reason
Use Situation: General Mountaineering..
I purchased the Elios after I lost my last helmet. I got the green size two and have been greatly pleased so far. I have a large head(brain too I would like to think). I wear about a 7 3/4 to 7 7/8 and the Elios fits like a charm. I am even able to fit a medium to lightweight beanie on with the helmet on. My previous helmet was a Grivel Salamander, and it was a tight fit with a hat on underneath. My one concern with the helmet is the location of the adjustment nob. If you feel the back of your head where the bump is in the lower center, that is around where the adjustment knob fits. I have a slight phobia of falling and hitting the knob straight into the skull. The helmet fits better with the knob a little lower than the back of the helmet, but I have this irrational concern that the location may be a problem. I would strongly recommend this helmet if you have had problems getting helmets to fit due to brain size. For reference my head is pretty narrow, but long if that makes a difference in fitting.
