Been using this helmet the whole summer. So far I'm loving the fit and weight. I wear a s/m and the two sets of pads allow you to really find the perfect fit for your head. The detox retaining system really works. It's a set and forget type so no more messing around with it after it's set unless your head gets really fat. It's so light weight that you forget you're wearing a helmet even after a couple of hours of riding. I'd definitely buy another one when this current helmet wears out. BTW, I also love how it looks, like a real helmet that doesn't make you look like an alien.
