This tag group allows users to filter all clothing products by gender. This means you can narrow down your search to only children's items or perhaps ladies or men's fitting garments. If your needs are for items that can be worn by both men and women then select Unisex.
Pair it with another filter group to be really specific - for example: men's, short sleeve, shirt.
The results will only leave products that match your criteria which saves your time browsing and reduces the page views required to select the best garments for your companies uniform.
