This has always been too small for me, I ordered a M in the short sleeve version that fit great but the sleeves on this model just don't work for me, I am a short torso long limbs type and my guns and triceps insulation make this too tight for riding. Worn twice, once as a fitting when it arrived and again this morning after I was cleaning out some cycling gear that I don't use anymore. Never actually worn on a ride so it's as new as you can possibly get, tags have been removed. Not sure what the cost new was but the design looks a million yen (okay it was 4,500), asking for 2,500 with free postage in Japan.
It's the design on the left!
