The Optimist buoyancy bags from Optiparts are made of polyurethane coated nylon and are about half the weight and significantly stronger than buoyancy bags made of PVC or PVC coated nylon.
Please note, do not over inflate the Optimist buoyancy bags. When bags are properly filled, they will be soft to the touch. Over inflated buoyancy bags may burst when heated up by the sun or rising temperatures. Make sure there are no sharp points in your boat that would snag or puncture the buoyancy bags.
