How Proof Plus Size Undies Work?
All of our plus size period underwear is made with several layers of materials in order to provide all-day protection. The layer closest to your skin wicks away moisture so you feel dry, followed by a layer of absorbent technical fibers that fight bacteria and odors and a layer that acts as a liner shield to keep leaks at bay. The outermost layer is made from water-proof fabric and Leak-Loc® edges, to guarantee coverage and protection.
