x Kappa Muscle Undershirt Summer Weight Mesh

The Attaquer x Kappa Muscle Undershirt is a sleeveless, summer-weight mesh base layer that wicks sweat and works year-round. Made from a hydrophilic fabric, it sits between your jersey and skin, drawing sweat away and cooling you as it evaporates in the warmest conditions. When the temperature dips it adds a light layer of insulation, while staying completely breathable.
