This mask inner is designed to be comfortable to wear, and it is also antibacterial, sweat absorbent and quick drying.
The Bretec(R) dry-up function reduces stickiness, stuffiness and unpleasant cold when wearing the mask, making it comfortable to wear.
By using the included mask to prevent slipping, the mask and inner layer firmly catch the mask so you can rest assured that it will not slip or fall off when you are talking or taking it off.
