The colors and design work of the Sabres makes for a FANtastic-looking jersey! New-with-Tags, this is a size Large. It measures 25 inches straight across from underarm to underarm (50 inch chest).......and the jersey is 35 inches long. It will be my pleasure to serve a fellow Sabres fan. HAPPY SHOPPING ;-) p.s.....you'll be receiving a fabulous Sabres Christmas hat as a Bonus ;-)
