Ordered a large for my 34" waist and they are very tight. XL would be preferable. I do not like the trend of a thicker chamois. This one has variable thickness which makes it ok (not great). The part that disappointed me the most is the seams. They are not flat. After a 40m ride, I had sore "stripes" on the front of my hips and legs where the seams were. Also, the stitching is coming apart on one side of the chamois. I expected more at this price point.
