LG XS standard fit is getting close - looks and feels good standing, does not expose my pale underbelly if I lift my arms, pretty uniform fit. A little loose up front in a riding position but miles better than a medium. Riding my pockets stay put in the middle of my back where they should be which is also an improvement. Comfortable at an endurance pace or short ride to work. A keeper. Up front it still flaps enough I'll keep looking for a better fit (more jerseys are on the way) for fast rides or just get mediums tailored.
Sized for 35-37" chest, 29-31" waist, 35-37" hips according to the manufacturer which is spot-on.


As a 5'10" (average height) guy, medium build, not skinny enough to have veins popping out I find running out of sizes absurd.
