The Hinman is a self-inflating, high-density foam core pad with a two-way adjustable valve that makes inflation, deflation, and micro-adjusting the firmness easier than ever. With options for 1.5 and 2.5 of cushioned thickness in a variety of sizes, these pads are a great choice for those looking for a durable pad for supreme insulation in colder temps (for max insulation in cold weather we recommend pairing with a closed-cell foam pad like our Third Degree). The stretchy, soft polyester exterior fabric makes for a soft, cushiony yet very durable sleeping surface. The Hinman is available in a 50x78 size which pairs well with the Dream Island 15 doublewide bag.
