I am selling this item because I purchased it this year, tried it on, and it was a bit tight. It's similar to the Millet mesh. This base layer is made of 100% polypropylene, which has moisture-wicking properties. The body is constructed with a honeycomb mesh structure for high breathability and excellent skin separation. It quickly releases sweat while preventing rewetting. The shoulders are reinforced with a jersey knit for abrasion resistance. The seamless, circular-knitted construction of the side panels eliminates uncomfortable seams. The highly stretchable fabric fits the body while following complex movements. It is treated with Polygiene to inhibit the growth of bacteria on the fibers and reduce odor caused by sweat. Comes with a convenient net case for washing and storage. ■Color: K (Black) ■Size: L-XL (Body length/62cm, Body width/45cm, Shoulder width/43cm
