The Scuttlebutt from the Human Bobber Line at H3O Sports is multifunctional. I use it as a kayak seat which is super comfortable and supportive. I often kayak to the sandbar where I then reconfigure the Scuttlebutt into a float. It can either be worn around your waist, which allows me to bob in the water, or it can be reconfigured into a water seat where I recline.
I love this product! Great for kayak enthusiast and highly recommend. Great quality, great price, and you will use it constantly!
