Family fun in all forms--especially the circular kind--is a sure bet with this giant sports tube. The extra-heavy 20-gauge vinyl bottom stands up to rugged use while the dual permanently bonded handles provide firm hands-on action. The tube features heavy-duty recessed marine safety valves and an inner safety air chamber. Use it in the family pool or pack it up to take along on the family vacation. Makes a great leisure float as well. 54 dia.
