this helmet fits well and provides great protection. The other day I went of a kicker and landed backseat and hit my head pretty damn hard, and although it hurt if i had worn my old smith helmet i would have easily gotten a concussion(it was very loose and thin layers of foam for protection. I enjoy the red phone capability, but it is hard to turn on and off for talking to friends when skiing, so i usually use any spare old headphones with a mic to answer calls. i reccomend having a volume and pause button on the headphones. overall the helmet was a great well fit choice. i reccomend using the sizing charts on the site because they are most likely correct with the size.
