About 95% of the time I wear a HD 1/2 helmet. For winter weather I also have a HD full face. The full face helmet was an expensive unit that was on the discount table that I picked up for $50.00 so I don't have a lot of $ in it but it is nice in cold and or rainy weather. No matter what you do sometimes you get the ole itch head, but I have found it helpful to remove my lid when we stop for gas or just a little rest or water, no matter how short the stop will be it seems to help. If you don't already do that. Oh the reason for the half helmet is, it is cooler and easier for me to turn my head to check for cages in the blind spot. I possibly would not wear one very much at all but we live in a must wear state and are surrounded with states with the same law.
