When it comes to protecting your patio furniture and grill, these covers are essential. Designed with water-resistant fabric, our covers come with ultrasonic welded seams, which is a handy technology that binds the fabric seams together with no sewing or stitches involved. No stitches in the fabric = no holes for water or rain to leak through! Combine that with breathable fabric and a one-year warranty, and youve got a perfect cover for the outdoors.
