Awesome! The material is such good quality - the light colour is only slightly see through with bright coloured undies, but I did get a pair that are quite tight as I prefer a firm fit while running. I wear these for running and they are perfect - do not slide or move at all, and are long enough that I do not get chaffing on my long runs. I am an Aus size 10 and usually get a medium in pants, but there was only a small left on sale so I risked it and got the small. They fit fine, but I think I’m future I will get the M. They are not too tight at the base so do not make an weird skin bulge at the edge of the short like some brands do.
