Weaknesses: Too small around the thighs, hot (no air flow).
Started the ride and the shorts seemed to fit. After a few miles the sound of the material rubbing aginst my seat started to get annoying. As my legs warmed up (the shorts seemed to have no ventilation) the liner and bottom rubber elastic got too tight. About 7 miles into a 12 mile ride I actually considered riding home without pants. After paying $50 I'm thinking about cutting out the liner and seeing if they are any better.
