I don't want to be a jerk to those who disagree, but I think any experienced rider would never want to ride without a full face helmet. I'd honestly probably rather be dead than to have my entire face crushed in an accident, and I think people who wear half or even 3/4 face helmets have never been close to someone who has died from inadequate helmet protection. Unfortunately, I have, so a full face is the only option for me and my (very infrequent) passengers. You know what feels better than the air rushing over your face? Being alive.
