We offer Drop-Stitch Inflatable Water Floats. Drop stitch is a material that allows inflatable structures to be made with 100% flat surfaces. This makes them far more rigid and sturdy. The fabric is made by joining two external pieces of material using thousands of fine polyester threads that are tightly woven together. When you add air, the threads are pulled tight, which creates a sturdy surface. TAKE YOUR PARTY TO THE NEXT LEVEL.
