Our outdoor mats feature a textured unwoven fabric top paired with a sturdy recycled rubber backing, offering reliable traction and durability for everyday use. Designed to resist fading from sun exposure and wear from the elements, each mat brings a splash of color and function to entryways, patios, or porches. Printed in the USA with weather-safe inks, they’re a practical and stylish way to welcome guests season after season.
