best and cheapest
rode Nebraska-to-Alaska last summer. Threw in a set of ear plugs (that right less than $1 cheapies) as an afterthought. In Alaska some places the bugs were so thick they rode the air stream up the inside of my helmet and straight to my ears. Stop FAST!! take off helmet and remove bugs. Did that twice then never went anywhere without the ear plugs in. Best pieces of equipment I took with me on the trip and cheapest.
