Inflatables, also known as the ducky, can usually be transported by hand using a carry bag. They are made of hypalon (a kind of neoprene), pvc, or polyurethane coated cloth. They can be inflated with foot, hand or electric pumps. Multiple compartments in all but the least expensive increase safety. They generally use low pressure air, almost always below 3 psi.

Until recently, inflatables were non-rigid, essentially pointed rafts, and best suited for use on rivers and calm water. However, recently some manufacturers have added an internal frame (folding-style) to a multi-section inflatable sit-on-top to produce a seaworthy boat. Besides being portable, inflatable kayaks generally are stable, have a small turning radius and are easy to master, but they take more effort to paddle and are slower than traditional kayaks.
