+ 1 on the Duluth Trading Firehose jeans
If you looking for a bang for your buck for a pair of protective riding jeans the Duluth Trading 5 pocket firehose jeans are the best. I also had a friend lay down his ride and said he slid at least 15 yards on asphalt and got up without a bit of road rash on his legs or butt, he is a firm believer in those heavy cotton jeans and I also bought two pair after seeing his and they were not even close to being destroyed. He still uses them and they are in fine shape. They are very comfortable for a heavy jean.
