Unfortunately I cannot rate performance, because it runs smaller than the sizing indicates. My son's head measures 22 1/8" or 57 cm. I purchased the size Medium which claims to fit circumference 21.8 to 23.2" We're good, experienced skiers and we know how to fit our gear. He's worn Giro helmets in the past that were a good fit for his head shape. This one just seems to run small, and doesn't have a great adjustment system. The sizing is done by pad fitting, which would be fine as the large adjustment gears at the base of the head, and the plastic harnesses can sometimes be uncomfortable. He put the helmet on as it came, without adding any additional padding and it was just a bit too tight. Meaning it probably fits about 22" without additional padding. There is no pre-installed padding to remove to increase the size, just thicker pads to add to decrease the size. Otherwise, the shape and fit was OK, but at 13 he's not full grown, and I wanted a helmet with the extra inch to inch and half of growth in it. I would exchange it for the size Large, but that isn't available in the color he wanted. If the size were as described, it should've been a great helmet. Removeable earpads are great for winter & spring skiing, goggles clip was adequate, it was light weight and comfortable, and expected the ventilation to be adequate but could not verify the goggle compatibility/anti-fog feature.
