The triple-layer quilted wave knit achieves high heat retention. By creating a large air layer in the fabric, insulation is increased, preventing cold air from entering from the outside. Dantron(R) used on the skin side has a low thermal conductivity, so it does not allow body heat to escape. The specially quilted wave processed fabric has excellent elasticity, providing comfort without restricting movement or causing a tight feeling during exercise.
