The patented No Sweat Liner by Headline It is an essential product for any wig wearer. Each package consists of 10 disposable sweat elimination liners. The individually wrapped packages are small enough to take with you anywhere and discretely packaged for your convenience. The nude back layer is great for camouflaging the liner under wigs and headwear. The unique combination of micro-fiber materials are engineered specifically for your needs to stay dry and comfortable. The moisture transport system quickly draws perspiration away from the skin, wicking it into the transport layer.
