I have always used either universal-sized bike helmets, or adult male average-sized ones. They've always been fine and seemed to fit okay, depending on the helmet of course. But when I actually measured my head before buying this one I was surprised at the sizing. I honestly thought that my head was of a normal size but apparently it is a bit on the small side. I considered just going with an average size despite their sizing but I am glad that I went with what they recommended for measurements and got the smaller size, which fits my head like a glove, even though I wear a skullcap between my head and the helmet. I am not sure whether this is because it is a high-quality helmet or whether the size is the big factor or whether it is just the perfect design for my particular head. It is the most comfortable, and most secure feeling helmet I have ever had. The MIPS gives me a little peace of mind, as much as can be while riding on the road I guess. And the yellow around the bottom edge makes it very visible. The strap system is pretty standard as far as I can see and works perfectly, no slipping. And the ventilation holes seem to be just the right number. I was able to attach a minimalist helmet mirror with no issue (velcro). Great helmet, I highly recommend it. Read more

Love the Quality; fit, comfort, adjustability, light weight, style. Tried many brands / models and this one fit perfectly right out of the box. It is sized better than the "universal" ones that fit head sizes from small to large. great price on amazon.. Read more
