Typically I don't wear a helmet, but if I am somewhere that requires me to wear one or I just feel like putting one on one day, I will wear a half helmet.
Used to rock the full face when I rode a Honda, and used it to bring the Harley home and quickly realized I need a shorty. Just think it looks goofy when riding a Harley, but that's just me and thumbs up if you do, your smarter than me
Despite the fact that we HAVE TO wear a bucket; I would still wear one even if I wasn't mandated. Usually 1/2 helmet for seasonal every day riding and a full face if it's late in the season or on the highway when the skies open up!
I wear a half with a built in pull down visor which is really nice for day time riding as it is tinted and I can wear my glasses. otherwise at night I wear goggles with it
I vary. I commute to work on the highway everday in a full\modular. I use the half for group back road rides and the 3/4 for all else. Honestly, the 3/4 is probably my favorite only as it actually allows me to hear better, stereo included, and doesn't block vision etc.
Depends on the situation, but I primarily wear a 3/4 helmet now. I'll wear a full face if it's cold or I know I'm going to run into rain. I also have an AK-88 half that I really don't use much anymore unless I'm on the big bike.
I probably have six or seven helmets. I have a hard time finding a helmet that's comfortable. I usually prefer a half helmet, but I bought a full face/modular helmet this winter to do my motovlogs (I wear glasses, so the modular/flip up helmet helps me get my specs on). I had never owned a ff helmet in my life (and I'm old). I really enjoyed the ff this past winter--and it has kept the pollen out of my face this spring. It's kind of been my go to helmet here lately. That will change when the Carolina heat gets here, though. I'm thinking about one of those 3/4 retro helmets with a face shield when summer gets here.
