I got these knickers for fall/spring riding when it's too warm for my PI Amfibs but too cool for shorts. I wish they came with a no chamois option so you could wear shorts of your choosing underneath if you wanted like my Amfibs do. I probably would've kept them if they did. The chamois was just too uncomfortable in the crotch. It felt like my fellas were being squeezed a bit too much and not in a good way. I bought according to the size chart and everything else about them fit fine. 5'8, 32 inch waist and bought a small. The straps were comfy and the leg grips were as well. Maybe with a bit more use the chamois would break in some but it was just to uncomfortable to try. I returned them without riding in them.
