The jacket was once for about 35 miles and shows no signs of wear only one flaw that I noticed is a 1/2" of unseen seam at the left cuff.  Dimensions are approximately:
All measurement were done with the jacket flat on floor.

Chest pit-to-pit = 26" (52" total)
Front/Main Zipper = 23"
Back collar to waist = 33"
Waist = 22" (52" total) adjustable downwards via Velcro loops
Sleeves inner = 19"
Sleeves outer = 25"
Sleeves from center of collar to cuff = 37"
