This is an undershirt (inner shirt) from UNDER ARMOUR. I am selling it because I have stored it without wearing it much. A classic ColdGear model that is warm and easy to move in with just one layer. ◆ The waffle structure's unevenness creates a layer of warm air between the skin and the wear, making it warm enough with just one layer. ◆ The brushed (fleece) back creates an exquisite feel and comfort like fleece. ◆ Excellent stretchability that flexibly responds to intense movements. ◆ Cutting pattern that reduces the "feel" against the skin. ◆ Logo embroidery on the neck. ◆ Excellent 4-way stretch for smooth movement in all directions. ◆ Quickly absorbs moisture from sweat, releases it to the outside, and keeps the athlete's body dry at all times. ◆ Cuts over 90% of UV rays and protects the body. ◆ Suppresses the growth of bacteria that cause unpleasant odors and exhibits an anti-odor effect. Material: 65% nylon, 21% polyester, polyurethane - Brand: Under Armour - Color: Blue - Design: High neck - Style: Long sleeve - Features: Fitted design
