There's a product out of South Carolina, butt buffer. It is hospital bedgrade material covered with velvet. Three sizes, and heavy enough to sit on the seat by itself or it has two straps that attach it under the seat. Couple guys turned me on to this on the ride back from Sturgis. I keep it in the saddle bar and usually lay it on after a couple hundred miles. Also, startedusing medicated powder in my shorts. I carry ear plugs if needed.
