The ThermaSeat Infusion is a “triple threat” cushion that features a three-layer design that keeps hunters’ backsides warm and dry. It’s made of a 3/8-inch layer of Softek closed-cell foam for maximum heat retention, a 1 5/8-inch premium, furniture-grade urethane Comfotek foam for comfort, and a 1-inch layer of rigid polyethylene foam that provides protection from the cold, wet ground. Each Infusion cushion is covered with waterproof, freeze-proof, polyurethane-coated SilentTouch fabric and comes with an aluminum carabiner clip, making it quiet and easy to carry. Lightweight and built to last, the Infusion features a breathable mesh for added comfort, military-grade hardware, webbing and a rubber-coated non-slip base. Available in Large (13x14x3 inches) and Big Boy (13.5x17x3 inches) sizes. MSRP: $32.99/Large; $63.99/Big Boy. Contact: www.thermaseat.com
