It is my first helmet, although I've been skiing for quite a few years now. Before buying the G10MX, I was checking out a few other brands, but they all seemed more uncomfortable. I had a lot of difficulty deciding my size. According to the size chart, I should be M, but my measurement of the head is just lower than L, so I had to go in a shop here in Japan and measure both M and L from the G10 series. My suggestion is if you are between sizes, buy the bigger. Otherwise I have been wearing it for 3 days in a row, and it feels great. When I'm walking though, my head starts sweating almost immediately, so I'd say great for skiing, and almost great for just moving around in low speeds. If you like the design, buy it. The price is very reasonable.
