This is a short-sleeved mock neck shirt from ANSUNESS. I bought it for this summer, thinking a looser fit would be nice, but the M size feels a bit too big for me (154cm, 43kg), so I'm selling it. UV cut Sweat-wicking Stretchable. The side tape is also cute! I haven't worn it on the course, but I have washed it once. Shoulder width: 37cm Body width: 45cm Sleeve length: 15cm Length: 37cm Pattern/Design: Solid Pattern/Design: Print (logo, etc.) Color: Black
