NWOT Sugoi Piston compression long sleeve

This ultra-compression long sleeve by Sugoi is a part of their Piston line meant to help keep your muscles from fatiguing while completing your triathlon, long run, ride, or other high-intensity activity. It's never been worn as I bought it at the warehouse sale and didn't try it on. Size is M but it's more fit an athletic S or a comfortable XS. Can fit a medium of you like very fitted compression (some people do, just not me). From a smoke/pet-free home. Check out the compression leggings too!
