A common mesh material used for hair system bases. It is typically a finely-knit polyester or nylon multifilament thread in a hexagon pattern, and allows natural scalp to show through the material, so the hair in the hair system looks like it is growing out of the scalp. It is very breathable, allowing water and sweat to pass through the material. Should not be worn over growing hair. Can accommodate a poly perimeter for easy cleanup if desired.

Liquid adhesive
