Navy undershirt featuring ColdGear technology, providing a comfortable fit. - Brand: Under Armour - Model: ColdGear - Size: MD/M/M - Color: Navy - Material: 87% Polyester, 13% Polyurethane Thank you for viewing. Due to a growth spurt, it was quickly outgrown, so I believe it hasn't been worn much. Shipping is planned via Nekopos (domestic Japanese postal service). The condition is good, but it is a used item, so please consider this if you are interested.
