Swimways's Sea Squirts Life Jackets are fun and kids love to wear them. They are easy to zip and clip and are shipshape enough to qualify as a ski vest or wake-boarding vest. They are U.S. Coast Guard certified as a Type III Personal Floatation Device. The arm-hole sizing insures a proper comfortable fit so the strap between the legs doesn't have to be too tight. Sturdy Grab Me Fin and professional neoprene construction make this a comfortable and fun life jacket for kids. Patent and Patent Pending.
