Finally, a mat that really is big, water resistant and easy to fold! Having been frustrated with most large picnic mats out there that need to be folded up in the exact same way, designed picnic mats with an adjustable strap so that they dont need to be folded in any specific way. Just fold or roll it up however you please and adjust the strap to suit. The water-resistant fabrication makes it the perfect partner for the beach or park and squishy foam lining makes it soft and comfortable to sit or lay on. Polyester water-resistant back keeps the underneath dry. Comfortable foam lining allows for long days lounging at the beach or park. Convenient adjustable straps make it easy to roll up and secure. Size open: 2m x W 2m. Size folded: 37cm x 27 cm x 9cm.
