I am kind of on the fence when it comes to helmets. At a certain point a helmet becomes useless. At around 15-20 MPH a helmet is not going to protect your brain (believe me). For a long time I refused to wear one, I have seen people die from head trauma while wearing a helmet. However I do see a purpose to them when it comes to low speed incidents in an area where there is a very real possibility of hitting a rock or tree. Don't think that because you have a helmet on means you can crash hard with no consequences.
That being said, this is a very comfortable, well vented helmet. I would highly recommend it.
