Black Diamond updated the helmet in 2012. It now:
- Comes in two sizes: S/M and M/L
- Is 1.5 ounces lighter
- Has a more precise adjuster wheel
- Comes in new colors
- Has more vent holes
- Has new headlamp clips
They did not change the price ($60).
The Half Dome excels as one helmet for all occasions from moderate free climbing and ice to big wall nail-ups and alpine. The Half Dome is the same price as the CAMP Armour and Mammut Skywalker 2 and slightly less expensive than the Petzl Elios, which is a similar design and offers a slightly different fit. Try on all four. The competition is so stiff between them that is hard to recommend one over the other. If you want the ultimate lightweight helmet, go with the Petzl Meteor III Plus.
