" I use this helmet for my daily commute, it's very comfortable and easily sized to get a perfect fit. I was worried it would be too small, as I'm 6'6", but it actually fits perfect on the largest setting. Great service from the guys at All Terrain Cycles - recommend shopping with them and buying this helmet. "
