Many of you already know that our "Tour Back" is an instant (just strap it over the hard plastic back) comfort fix for the Tarpon series of boats. It is constructed of the soft, self-contouring thermal-molded foam used in our top-of-the-line GTS seats. This kayak seat is manufactured from the soft, self-contouring thermal-molded foam that we use in our top-of-the-line GTS seats, making it very durable and long lasting. The thermal formed seats have great performance characteristics when used in kayaks due to the nature of the foam. We use cross linked closed cell EVA foam that is laminated to the fabric under 60 tons of pressure and 400 degrees of heat making it essentially a permanent bond. This compression molding process eliminates water entrapment between the foam and fabric- a common problem in standard cut and sew kayak seats. The process makes the seat virtually waterproof and a whole heck of a lot stronger. This back rest has a molded in cavity that securely attaches to most existing plastic back rests. It comes with webbing and adjustable side release buckles. The Tour Back Rest is 10'' high and 14'' wide. This kayak back rest offers a storage pack that offers 320 cubic inches of storage. This back rest was originally designed and to go with the Tour Bottom Pad # KTR604.
