I'm new to the sport (working on my post AFF jumps) and I've been given permission to wear a full faced helmet. I made a trek to Chuting Star and tried on all their helmets. I found that I must have a massive skull because I was in the largest sizes of all the different brands. I ended up going with a XXL Cookie G3. My only problem is that the chin strap is extremely tight. When I get it on, its hard to swallow. I have the strap at max length. Is it possible to get a longer strap? or has anyone found a way to extend it?
