Come and see our amazing products. This item is made of premium PVC material with a strap which can be wrapped to your body. The Swim Bubble gently tows behind you without pulling you back or adding extra drag to your swim. The Swim Bubble provides reassurance for safer swimmers by adding extra visibility and floatation, in case you cramp up or simply need rest. The Swim Bubble is light so it will be easy to bring with you on a paddleboard or kayak trip. While the New Wave buoy and bubble safe swim series add to your swim safety, they do not replace a personal flotation device (PFD) or a life vest. If you need bigger size, welcome to enquiry. Pls confirm with us about the packing info, stock status and exact production time before placing your orders.
