Always taken off pretty much immediately after a ride and hand washed in PerWoll sport detergent.  Drip dried in the shade so the deep blue color is as vivid as the day they were made.  Zero blems/pulls/broken stitching/stains/weak elastic etc etc, not even any chafing where the shorts meet the saddle.  Sizing is pretty straightforward: true American fit.  Only selling because I lost alot of weight and am now wearing M cycling clothing.  Please check out my other cycling goodies and I'm happy to answer any questions.
