In
providing our customers with the safest product possible, we have designed the
Dura-Bladder (now patented). It offers the uniqueness of high tensile strength and
excellent abrasion resistance. The bladders are scientifically designed to
essentially self-close small punctures while anything larger is easily patched
with a controlled heat source. Even with the valve open, the Dura-Bladder
provides sufficient floatation for this 6'4", 220 lbs man to stay afloat.
