The $90 PI Ultrasensor shorts are cheap by my standards, cheapest I can tolerate, sagging like a diaper and not feeling all that comfy. I use them for my shorter riders. The $150 PI Ultrasensor 3D Pro are still my favorites, conforming to my body much more closely and not feeling too thick. The Assos F1.mille are my 2nd choice, also around $150, but a little thick for my tastes, and the leg cuffs irritate the back of my leg where they are stitched. My conclusion after 4 years of riding is that cheap is an illusion. You get what you pay for, and paying less money for something that is constantly irritating and uncomfortable is a false economy. Also, alot more precision and hand detailing goes into these things than you might suspect. Can't throw them together with loose tolerances and have them consistently fit well, like you can a T-shirt. Plus, they are manufactured in lower quantity, having less economy of scale.
