Solid Helmet, Very Lightweight
I started wearing a helmet this year because it is just the smart thing to do. I was worried about a helmet feeling bulky or constricting, but after an hour on the slopes, I did not even notice it was on. The G10 is nice and warm for the coldest days with removable earpieces and adjustable vents for when the weather heats up in the Spring. The G10 fit me similarly to the G9. (There is a definite fit difference between the G9/G10 and the Giro Fuse). The G10 has a slightly sleeker look (think "new school style") than the G9 and has the adjustable venting via a switch on the top of the helmet which makes temperature regulation more convenient than with the G9.
