For what it’s worth, iv tried one on a few times and I was very impressed with It, very comfortable, didn’t feel heavy and felt better on my head, and felt very good quality, including the drop down visor.
I use a large in shoei neotec and gt air and the large was perfect. Arai/Schubert’s/shark etc do not fit my head, only shoei, hjc and nexx and I have honestly tried an awful lot.
Will be considering one for my next lid, just not sure if I really like any of the graphics too much.
