This picnic mat is constructed with a polyester surface and a PVC waterproof backing, designed to keep you dry on damp lawns or sandy beaches. The size of 203 cm by 152 cm accommodates three to five people. When folded, it compresses to approximately 18 cm x 30 cm, resembling a small handbag. The material is not recommended for machine washing; hand washing in soapy water and air drying is advised. Uses include beach blanket, camping blanket, baby play mat, yard blanket, emergency blanket, or throw blanket. It is suitable for picnics, fishing trips, sporting events, concerts, and hiking. The surface is durable for regular outdoor activities. We suggest spot cleaning after each use to prolong the life of the fabric. Do not leave the blanket exposed to heavy rain for extended periods.
