Castelli Men’s long Sleeve Cycling Red/White/ Grey Jersey with Scorpions logo. Full Zip. Rear Pockets. Showing size XXXL- but my son wears this jersey a few times and he is US large. Maybe in the Cycling world if the rider tall and skinny this jersey will feet the size showing of 3 XL will be just about right. Anyway please review all the images. There are some images showing measurements. Otherwise the Jersey looking excellent. The pre owned condition is super. Enjoy it soon. Fast shipping.
