The latex is encased within polyester in such a manner that at no time, even when fully stretched, is visible; nor does it come in contact with the skin.The first layer is changed from cotton to an open-cell urethane foam.The urethane layer has several advantages over the original cotton layer. The open-cell urethane is breathable, more comfortable, moisture-wicking, and hypoallergenic (so it can be worn directly against the skin). Plus, it conforms to body curves better. Due to it\'s tacky nature it grips so well that it will not move - even on the most active peopleNo other portion of the belt or packaging contains latex. Additionally, the two pieces of the 1 x 6 inch mesh, non-slip material, on the inside of the cotton webbing is made of a polyester fabric knit with vinyl coating.
