Available for most models, the Inlet Plug protects against the elements. It crafted with red Aqualon fabric, which makes them resistant to mildew, abrasions, water penetration, most petroleum products and UV exposure. Plug is sewn with GORE Tenara thread, a non-aging thread that withstands the elements, even after years of exposure. Compared to others, Kennon's plugs withstand the weather longer, so you will be using them long after the competition's wear out.
