The absorbent gusset uses what we call TriTech performance. Comprised of three layers: wicking, absorbent and breathable. The wicking layer is made of modern technical fabrics which draw moisture away from the body – similar to sportswear. These fabrics are made from high-tech polyester which, unlike cotton, quickly transport fluids into the absorption layer to feel as dry as possible on the surface. Additionally, the gusset is sealed around the edges, so you can trust it to keep your fluids in.
