"These Crewsaver Buoyancy Bags are tried and tested and come in a wide range of sizes. They are made of a polyurethane coated nylon material with extra wide heat sealed seams to produce a long lasting, abrasion resistant and lightweight buoyancy bag. All are Yellow, with a large one-way valve and loops for tie down webbing. Thirteen different sizes to choose from. Two to three webbing straps are required for installation.*Tips on Buoyancy Bags: Make sure there are no sharp points in your boat that would snag or puncture the bags (especially check the undersides of any structures). Bags should be attached to the boat by passing webbing straps over and around the bag through the positioning loops on the bag. DO NOT use the loops for the actual load bearing attachment to the boat. Leave your bags slightly underinflated to ensure they do not rupture as the air inside expands on hot days. All dimensions quoted are approximate inflated sizes. Buoyancy is approximate as provided by the manufacturer."^^<http://www.w3.org/2001/XMLSchema#string>
