OMG these feel good. No seams and perfect leg grippers - none - the material is just a bit thicker and stays in place. Very lightweight so best for warm to hot days, although compression is pretty good despite thin material. Runs slightly small. I am 5'6" 29" waist 139 lbs and the small works for me. The straps are a bit flimsy and tight but I always wear a baselayer and I am on short side so not a problem for me. If you are tall they might dig in a bit. Superb chamois. Have held up well to repeated use but would not call these everyday bibs.
