Louis Garneau Zone3K found on TE, are wonderfully comfy. Material is not shiny lyra but stretches just enough. The chamois is the same one in the neo power LG short that many people like. The yoga waist doesn't cut into your middle, but lets you breath. I have the neo LG short, but it isn't near as comfortable around my middle.
The length isn't as long as some cycling shorts. Info says 5 1/2". I think my size L seems longer than that because I don't like shorts to be too short, but these seem o'k.
