Me - 5'9/158/31" waist - Ordered a med which fit well, snug but not overly so. Fabric felt great, good compressive support, straps were perfect length, however the leg grippers set my skin on fire! The band has aggressive stitching above and below the silicone gripper band, and the bottom seam, in particular, created a red line that traveled down below the hem the longer I rode. They were okay for the first ten miles but were nearly unbearable by the end of 45 miles. Sad to have to return them as I really wanted some Pinarello bibs to go with my ROKH. Overall, I liked Giordana's quality and will look for another pair of bibs with a different leg band.
