Materials & Care

Top: Polyester with Thermoplastic Polyurethane Skirting: Polyester and Spandex For best results, we recommend you machine wash on cold and tumble dry low. It will be tempting to wash and dry on hot — resist this urge! Heat drying could cause delamination and shrinkage. We want your protector to last as long as possible. You may also opt to air dry. We do not recommend dry cleaning the protector. Do not use solvents, bleach, or fabric softener.
