Flotex Foam is most often associated with yoga mats and camping pads, but can be used for many other applications as well. With a squishy texture and medium-firm feel, Flotex closed-cell foam is a perfect material for boat cushions, life preservers, and more. While not UV resistant, this foam is certified by ULC (Underwriters Laboratory Canada) for flotation, and weighs 3.6 lbs/ft³.
