Speedo Deluxe Ventilator Mesh Bag. Speedo's newest mesh bag. Following the classic shape of the standard Speedo Mesh Bag, it has been evolved with new styling. Following the popular style of shoulder straps for backpack carrying, it is a robust and practical option for carrying your swimming kit. Mesh panels increase airflow to assist with drying. The clever zipped design means the bag folds flat and features a front zip pocket for storage. The drawstring closure keeps your kit secure.
