The "Ol" Mama Hen" features Hunters Specialties exclusive Infinity Latex, the most durable and consistent latex available. Infinity Latex calls sound great right out of the package and dont require a break-in period like other diaphragm calls. The tape used in the calls is water resistant and will hold up through an entire season of calling. The Ol Mama Hen is a 2 reed magnum reed call for extra volume.
