I've used Schuberth Flip helmets for over 15 years, but needed something lighter due to neck issues. 1st ride was an 1,800 mile tour of France in 35' heat. The helmet excelled, ventillation was good, fit was excellent and so light I didnt know it was on my head. Fitting a cardo that I ordered at the same time was a breeze. The service from sportsbike shop was excellent as always.
