The KoverRoos® Storage Chest Cover is the ultimate in furniture protection. Outdoor furniture covers need to breathe so that moisture can escape, keeping mold and mildew from developing under the cover. Koverroos® use technologically advanced materials that are one-way breathable - so moisture can evaporate right through the fabric, but water, dust and dirt can't get in. Also, these patio furniture covers are able to handle temperatures from -100 degrees Fahrenheit up to +240 degrees. This particular cover comes with a drawstring attachment system in order to secure the cover in harsher weather conditions and is fitted for an storage chest less than 54" L x 33" W x 28" H.
