Cold protection, moisture absorption, heat generation, sweat absorption, quick drying, UV protection, deodorization HEAT-X: Heat-generating functional material. "HEAT-X" is a moisture-absorbing and heat-generating material that absorbs moisture released from the body and generates heat. The unique function of the fibers themselves provides warmth to the material. DRY PLUS: DRY PLUS's unique functions and structure quickly absorb and release moisture. It has a structure that promotes capillary action, expelling moisture from the garment and allowing it to evaporate. This excellent ventilation system of DRY PLUS ensures constant circulation of humidity inside the garment and outside air, keeping the inside of the garment comfortable even when sweating. Wash & Keep Cut (UPF50+): Born from customer feedback. The UV protection effect of this product remains almost unchanged after more than 20 washes, compared to before washing. Deodorizing Function DEO-PARTS: Strongly adsorbs ammonia in the air and water. It has 5 to 20 times the adsorption capacity of conventional adsorbents such as granular or fibrous activated carbon. It also adsorbs amines. Being fibrous, it has a large surface area and a fast adsorption rate. The adsorption capacity can be easily regenerated by washing.
