Important when kayaking an enclosed kayak. They offer a paddler the ability to rescue their kayak more easily after a capsize and wet exit. They displace the water inside so the overall weight of the water inside the kayak is reduced allowing it to be dragged to a the bank or to perform a cross deck rescue at sea. Here at shore we stock a great range of Palm and Ruk heavy duty nylon and cordura air bags. If you are unsure what size to get for your kayak give us a call on 01243 647830.
