Pros: Affordible - Comfortible - Race Proven by Bode Miller, Beni Raich and the Japanese Ski Team
Cons: Hard to find dealers who carry them in the US
Overall a really great helmet. I'm biased at this point because this is my third, and I now think enough of them to have bought the Jamaican Ski Team junior version for my 12 year old grand daughter who is a serious skier.
Sizing and Fit - I wear a Large (60) and it's a true fit vs. other helmets I have had like Maplus, Alpina and Leedom, which ran on the tight side across the jaw line. Interior padding is very well configured, and padding around ears is on velcro, so it can be removed on non race days when the air is warmer.
Comfort Level - High - Can get warm on a warm day, but I have had no problems with being cold on cold days, or even really, really cold days. There is no gimicky ventilation adjustment system, just a very efficient design that maximizes airflow
Safety - All the requisite certifications for Europe and the USA - CSI, FISI, ASTM and EN. Chin strap is woven synthetic with a metal micro adjustable buckle surrounded by plastic - makes for really precise adjustment and has a one finger quick release.
Graphics - KIller! Unfortunately not all the versions are available in the US.
Where - I get my helmets from Race Stock Sports in Waterbury, Vermont - owner PJ Dewey at 802-578-3585 - PJ was the Lange Boot Tech for Picabo Street, and other Lange sponsored athletes on the US Ski team in the 90's and early 2000's. They don't come any better!
