Compression undershirt that supports performance improvement. - Brand: Under Armour - Model: HEATGEAR - Size: YM 135-145cm - Features: Compression - Functions: Moisture wicking - Functions: Temperature control - Functions: Ease of movement Purchased from Under Armour for 3520 yen. I ordered the wrong size, so it's unused. Please check the third photo for the size details. Because it runs small, children who are 125-135cm tall may also be able to wear it. Thank you for looking.
