This bagg is a travel “essential”. The 18” tall x 22” wide x 7” deep tote is cleverly stowed within its 8” x 8” outside zippered pocket occupying less space in your suitcase than a pair of socks. Unfolded the roomy tote is perfect for a trip to the beach or returning home with those unexpected "treasures". The pouch converts to an outside pocket when the bagg is expanded. Made of lightweight durable water resistant rip-stop nylon lined with PVC for added durability. This is an excellent bag to keep with you at all times during travel.
