Sugoi Evolution WSD w/ Ricaro chamois. Chamois has channels so it bends properly. Fabric is awesome. I have a large rear end and thighs and these don't bind (not too much sausage effect). The leg grippers have the Sugoi Logo printed upside down so if you don't like the rubber on your legs you can roll them up. I crash quite regularly (mountainbike) and they have not snagged or torn. Very comfortable!
