Seat Saver Custom Polycotton Seat Covers effectively protect your seats, provide a cool, non-sweaty surface that’s absorbent, and are extremely easy to install by hand without tools. The cotton “drill weave” fabric these covers are made of features a strong diagonal bias in the weave, creating breathability without compromising tear resistance and strength. You’ll find this gives you a greater level of comfort during everyday use - causing less body heat retention, sweat, and stickiness typically felt with seat covers made from other types of materials.
