This is a KEER men's compression inner shirt. It has moisture-absorbing and heat-generating processing, with the function of absorbing sweat to generate heat and keep you warm. The compression lines correct posture and help with training and body shape support. It's a thin type that doesn't show through outerwear, so it can be worn under everyday shirts. Available in two sizes for men: M/L.
