A multi-layer bladder construct consisting of a non-stretchable outer covering and a stretchable inner bladder. The outer covering has an inner surface and is made from woven polymer fibers having a warp direction and a weft direction. The inner bladder is made from a bi-axially oriented polymer film. The inner bladder has an outer surface area that is smaller than the inner surface area of the outer covering. Upon inflation, the inner bladder stretches and expands until the outer surface of the inner bladder engages the inner surface of the outer covering, whereby a portion of tensile force loading on the outer covering is shared with the inner bladder. The multi-layer bladder was developed for use in air-inflated kites used in the sport of kiteboarding, but has broader potential application.
