The construction of our French Drawn top offers the ultimate in wig comfort. The beautiful details: Each wig is crafted with three layers of material – two outer nylon silk layers and a Swiss Lace layer in the center. The knotting method is state-of-the-art wig making, resulting in the most natural looking wigs on the market today. Hair is knotted on the middle Swiss Lace layer and then pulled through the super-fine nylon silk mono top layer. Knots in the middle layer are invisible, which gives the appearance of naturally growing hair.
