Fit on the AFX 37 and 39 can be hit or miss I find.
Aside from the standard feel of a $120 helmet, if there is a complaint, the most common on the 37 has been pressure on the forehead. Again, either hit or miss. Say 20% put the helmet on and immediately talk about forehead pressure. The remainder like the helmet, like the price and are instantly satisfied with all the money they didn't spend on the other models, possibly thinking of all the dinners out they'll have with their honey on the boulevard on saturday nights.
