These shorts are great for when your muscles are getting fatigued. The compression from these shorts are worth the higher cost and lack of a liner. The material seems quite silky and thin-haven't used them enough to know if wear is an issue.
This is the best pair of compression shorts I have owned. My only problem was that the sizing chart suggested I buy small but I had to exchange it for a medium. The small was too tight but the medium was perfect.
A nice enough pair of shorts--I wore them in a 4-mile race recently, and they were perfectly comforable--but I was expecting a bit more in the way of muscle support. I found them rather ordinary in that respect, and I'm guessing that less expensive options are available that perform similarly.
