All Onyx inflatable life jackets are U.S. Coast Guard approved and provide paddlers, anglers and boaters with plenty of advantages over more traditional life vests. Inflatables are low profile, comfortable, deliver superior in-water performance and ensure high visibility when inflated. These life jackets rely on inflatable chambers that provide buoyancy when inflated. And while they require a little more maintenance that traditional vests, inflatables can be rearmed in the event of inflation and are quick and easy to repack with a new rearming kit.
