Since our original RIVER OTTER was such a success, we added a backrest to the Deluxe to enhance comfort as you go riding down the river. This heavy gauge PVC tube has 2 comfortable molded handles and is great for rivers, lakes and pools. Slip on the protective double stitched polyester cover for a stable trouble free float in rough waters. A molded drink holder ensures that you won't go thirsty on your float down the river! Two rope anchors are sewn to the sides so that you can tether or link your 2 or more RIVER OTTERs together for the ultimate river flotilla! Equipped with a Speed Safety Valve for quick inflating and deflating. 48 in. (deflated) diameter.
