All these wigs offer some form of monofilament construction.
A monofilament top wig was designed to be 100% better for all wig wearers. The hair is hand knotted, one by one, onto the sheer monofilament top construction. This allows the flexibility to part the hair on the left or right or in the center. The mono cap breathes allowing air flow to the head. A monofilament top will give the appearance of showing the skin tone underneath from your own scalp.
These wigs will have a full monofilament top or just a part area and some will only have it in the crown. When you read the description of each wig it will let you know what form of monofilament it has to offer.
Monofilament wigs are more expensive. However, the cost is explained by the intensive work of putting the hair in the monofilament knot by knot – somewhat like crocheting.
