I have several skorts. They are all Terry Pro Race Skorts, so they are a little on the short side (so am I)... I've never had a problem with them getting caught on the saddle. I think that this is because they are a "wrap" type of skirt. I've mountain biked in "baggie" shorts before, and occasionally they would get caught. But because the hem of the skirt on a skort isn't sewn closed, when you get caught, it just pulls loose.
I did NOT make that clear, but in my head it makes sence to me!![]()
