I wear glasses and about a week ago got a FX39. Have just a little trouble getting the glasses on with the helmet on but I am coming from a HJC flip to this helmet. With just a week of wearing the helmet, I find it easier and easier to get my glasses on. I love this helmet btw. For me, no hotspots even when new. Helmet fits properly and I am looking forward to when I get it broke in as I don't care for having my cheeks pressed in so much (not painful, just tight). I bought the AFX over the Fly due to the strap connection on the AFX. It is a tab that goes into a ratcheting thingie. I can hook it up and take it off with my gloves on. Beats the crap out of the double D ring system the Fly uses.
I would buy this helmet again.
Nothing remains as constant as change
