IBKÜL garments are not to be put in the dryer as it's not a good idea to put any nylon/spandex based performance yarn in the dryer because it breaks down the fibers. This is true with most yarns of any nature. By putting the IBKÜL product in the dryer, the life of the special performance features our product offers such as color clarity, wicking, anti-microbial features and most important our IceFil cooling element, will be shortened. Please follow the handling instruction on the hang tag on your IBKÜL garment for best care.
