This Long Sleeve compression shirt is made of 88% Polyester and 12% Spandex. This composition of fabrics keeps your body cool by dispersing the sweat quickly and stimulates air flow. This fabric can efficiently pull moisture away from your body and then helps evaporate that moisture quickly, thereby creating a natural cooling effect.

When this material hangs loose and does not touch your body it can no longer pull moisture away from your skin.
