This is an adidas TECHFIT COMPRESSION short-sleeved top. The size marking on the neck has faded, so I'm not sure of the exact size, but it seemed to be about the same as the Under Armour compression T-shirt I'm selling separately. My son used to love this when he was 160cm tall. Despite being a compression type, this one has good stretch and is easy to put on and take off. The back is also made of mesh, so it can be worn coolly. It has been worn a fair number of times, but it is clean with no stains, dirt, snags, or peeling logos. There is a name written on it, which I will black out before sending it to you. It seems suitable for baseball and track and field. Thank you for your understanding of used items. ✳︎I will be listing several compression wear items. Please take a look if you'd like＾＾ Type: Inner shirt/Under shirt Sleeve: Short sleeve
