The helmet I wear and love in the hot summer days is the HJC IS-Cruiser helmet it has a pull down clear windscreen that retracts nicely into the helmet and can be pulled down to divert some of the bugs from hitting your eyes and face.Attachment 23150
it also comes in 6 different colors. Love this helmet and don't go out in the heat without it. You can get one without spending a fortune in price. I also have a full face HJC and never thought they were not up to the task at hand as they are very well built helmets.
