If you work around a pool, lakefront or own a pool you want to be sure to have safety devises in case of a water emergency situation. This is Kemp's most popular Rescue Tube. It comes with plastic squeeze style" quick-release clips. All Kemp Rescue Tubes are made of the highest quality closed cell foam to resist erosion. They're individually hand dipped three times instead of the customary two to ensure the proper adhering of the vinyl coating and to extend the useful life of the equipment dramatically. Kemp's shoulder strap is adjustable and goes all the way through the rescue tube. The edges on the tube are rounded, which is extremely important to prevent cracking and peeling.
