The Razor V-17 in an extremely sturdy sport helmet. In my mid-60s, I'm more than a tad concerned about taking a fall when I'm biking. Most of the bike helmets I tried on didn't adequately cover the back of the head. They were lighter, but, in my honest opinion, without value for a fall straight back. This helmet is a very close fit for me. If I had hair, it would be too small. The interior pads are removeable to give you more room, but if you remove them, the helmet is extremely uncomfortable. If your hat size exceeds 7 3/8 do not buy this helmet. Otherwise it's a very good buy.Because the helmet is black, I bought four orange reflectors and attached them on all sides of the helmet.
