[Features] Uses 3M's Scotchgard moisture-wicking technology, which suppresses stuffiness without compromising breathability. The fibers absorb moisture, providing a dry and comfortable feel, and maintaining the original breathability of the fabric while remaining lightweight. [Double Structure] A double-layer structure that traps air and prevents warmth from escaping. It creates an inner air layer to block out the cold from the outside, keeping you warm even when you move. [Fleece Lining] The inside is fleece-lined, providing a soft touch and excellent insulation for comfortable wear. [Stretch] Made with highly elastic material that stretches well and always fits your body. The skin-friendly flat seams provide a comfortable feel even when worn directly on the skin. [Note] This product is a top and bottom set.
