My ultimate favorite sports jackets (VSX)!! They hug the body just right and are pretty stretchy. It’s an XS but can wear up to a size M. If you like the slim/hug the body look. XS body hugging black sport’s jacket with thumbholes, deep side pockets, reflective back panels, and back zip pocket. 77% Nylon. 23% Elastane. Machine wash cold. Do NOT use fabric softner or bleach. Tumble dry normal cycle low heat. Do NOT dry clean.
