Stearns Sospenders inflatable life jackets are lightweight and comfortable, allowing freedom of movement while providing maximum buoyancy. Great for sailing, fishing, paddling, boating, or hunting, this Stearns Sospenders life jacket is stored as a compact belt pack, and manually inflates within seconds to be a complete, adult-sized (30"-52" chest) life jacket, featuring a convenient D-ring and storage pockets. Jacket inflates via the 33-gram CO2 cylinder by pulling the attached lanyard, or by blowing into the inflation tube. This Type III personal flotation device is Coast Guard approved. Uses rearming kit 0932 for repeated use. Inflatable PFDs are not recommended for non-swimmers; not for use for active watersports activities (skiing, tubing, wakeboarding, white water, or PWC).
