The select store "DRESSTERIOR" has released the "Cool Mask with Cooling Pack," which can be worn by inserting cooling packs into two inner pockets. The main body is made of a double-layered, stretchy cut-and-sew material that maintains a clean shape with moderate firmness. It also features antibacterial, quick-drying, and UV-cut functions.

Special sewing techniques ensure that the seams are not visible on the outside, creating a sleek appearance. Available in black and white, which are easy to match with any outfit, or in subdued all-over patterns. These masks are available on the official DRESSTERIOR website.
