The Ignik Backside 12-Volt Powered Heated Seat Pad delivers comfort and warmth on camp chairs, stadium seats, and bleachers. Ideal for camping, hiking, skiing, tailgating, hunting, and other cold weather activities where portable warmth on-the-go can transform the cold and wet to warm and cozy. Twelve-volt power means high performance and heat output (12-volt power bank sold separately). A handheld control with a digital display easily customizes the heat level, and includes smart features like heat-level memory and auto shutoff for power conservation; internal temperate sensors provide added control and safety. The dense foam cushion offers comfortable seating on rough, wet, and uneven surfaces, and the 100 percent recycled polyester outer shell is durable yet soft, designed especially for outdoor adventure. The Ignik Backside Heated Seat Pad is available in two sizes: Regular measures 16 x 12 inches and fits comfortably on a camp chair or single seat; XL measures 32 x 12 inches and is perfect for larger surfaces or sharing with a friend.
