The GTS Sport kayak seat is designed for the smaller paddler seeking extra support for their lower back. However at 12.5 tall the GTS sport kayak seat provides plenty of back support for any sized paddler and with its deep padded thermoformed foam panels this seat will self conform to each individual kayaker to create customized cushioning without compromising requisite firmness. This kayak seat has a sewn in oversized cargo pack on the back and, like all of our kayak seats, there are solid brass snap attachment clips on front and back. As with all of our GTS series kayak seats we use heavy duty 600 denier fabric wherever extra stress is apparent, {primarily the back of the kayak seat and the zipper pack attachments}, a combination of ultra soft, comfortable EVA foam for cushioning against the back and seat bottom and a PVC plastic foam combination for maximum back support and fatigue reduction. The GTS Sport has single easy adjust thumb operated tension locks on the forward adjustment straps and 1.5 rear adjustable hold down straps in the back. As with all of our kayak seats, this flexible attachment system works on most all sit on top kayaks. MADE IN USA.
