Our Beach Buddy is essentially a bean bag for the beach. The outer is made using a cotton breathable fabric which encases a mesh breathable bag filled with small polystyrene balls, the nature of the fabric insures that if the bag gets wet it dries quickly. For the closures we have used velcro insuring zero rust and ease of use. We have also included a handy pocket for sunscreen, phone etc as well as straps to make taking your Buddy to the beach so easy!!
