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 the outside. Dantron(R) used on the skin side has low thermal conductivity, so it doesn't let body heat escape. The specially quilted wave-processed fabric has excellent elasticity, providing comfort without restricting movement or feeling tight during exercise.
