I wear a full face with the sheild off and a pair of glasses underneath. It's been the most comfortable combination I've found. The helmet (Bell BTW) still flows plenty of air around your head with the sheild off, and most importantly it lets me ride windshield free 99% of the time.
Kabuto full face helmet. I've worn a f2f since I started riding in 1984, I'm a young one. The helmet has saved me from east from a straw twice. I'll keep wearing it no matter other people's thought on what a Harley rider should wear. Anyway, what's the saying, no face no case. LOL
I wear a classic Cromwell helmet with leather ear protection... In Belgium and Europe, it is not street legal anymore! But I like it and it fits perfect with my FLSTC!
Funny, I've worn a half for the past 20+ years and recently purchased a new 3/4 as I've been commuting more and more to work on the highway. I'm quickly getting used to the reduced noise, and the fact I can actually here BETTER with the 3/4 than the half; stereo and all.
