A particular kind of cap is included in a monofilament top wig, which is made to resemble the scalp's natural hair growth. A fine, sheer material used at the top of the wig cap is referred to as a "monofilament. "This breathable, frequently made of nylon or polyester material enables ventilation and comfort.

The individually hand-tied hair strands on the cap are the main distinguishing feature of a monofilament top wig. Each hair is meticulously tied to the monofilament material in this construction to give the appearance that it is growing out of the scalp. The hair can move and fall in a manner that closely resembles the movement of natural hair using this technique, giving the appearance more natural.
