The problem with riding in a kilt is two-fold, first there is the issue about the kilt flying up. the second is that it does not provided any protection in the case of an accident. When you get in an accident ( and if you ride you will eventually, there are only two kinds of people that ride those that have gone down and those that will). The two most common kinds of accidents are either a rider getting hit by a car driver that wasn't paying enough attention or a rider over estimating his or her own riding ability and incorrectly negotiating a turn or dropping the bike trying to park. Either the car situation or the over estimating often leaves a sliding down pavement or gravel or grass at a reasonably high rate of speed. any article of clothing that slides up exposes skin to the ground. When I used to ride all the time was before I started wearing a kilt, since that is now something that I enjoy and after a long ride I think that would be a lot more comfortable than wearing leathers all evening I would like to find a way to travel with them and have them look decent after a long day.
