The System Ofuton & Slim Mat is an adjustable comforter and mattress system designed in the style of a Japanese futon, with added functionality for improved comfort at camp.

The comforter is filled with hollow polyester fibers. It features six connection points for securing it to the mat, allowing the comforter to remain fixed in place for a comfortable night's sleep. Flaps on each side can be folded under before securing the straps, and a drawstring closure at the top of the bag can be tightened to maximize heat retention. The flaps can be secured at four points, on the top and bottom, for enhanced warmth and comfort.
