Ben Cookwrote a review of Giro Revel MIPS Helmet on May 8, 2017
Familiarity: I gave it as a gift but have feedback to share
I bought this for my 13 year old. He has a larger than average melon for his age. It is fits well with plenty of room for him to grow into it. It is a good looking helmet and as a parent the MIPS gives me a bit more peace of mind. The fit was easy to get dialed in. I got him the white helmet and he really likes it.
