Great helmet for climbing
The BD Half Dome helmet is my personal favorite helmet. It feels very comfortable and secure while climbing. It's very lightweight, easy to adjust, and stays in place very well for me and my buds who have it. The design itself manages to feel very durable without being bulky, and the ventilation is a nice touch to it. It's all around a very nice helmet and I am very happy with it. If you are a climber looking for a helmet, this is the one to choose.

Fits good once adjusted well
The helmet is light and breathable and it fits comfortably and snugly once you adjust the neck strap correctly. There’s a little strap in the back poking out that would interfere with a headlamp with a rear battery sitting correctly. Over great helmet though.
