Followed the link to the Nishua. Claims to be 1150 grams or 2.5 pounds. That's a full pound lighter than the helmets I've been looking at like the XD4. The Klim claims to be 3.25 which is still very light. Anyone know the true weight on the Nishua and can they be ordered in the US? I have some neck issues, so helmet weight is a MAJOR consideration in my search.
