Im running some RiverRoad throw over (pleather) bags. When I bought them a few years ago they were around $75 however I saw last week they are on sale for $40 through cycle gear. They are the compact plain style. Hubby built a brace and tied it into the luggage rack to keep the bags from banging into the side of the bike. Let me post a picture.
