The Hinman is a self-inflating, high-density foam-core cold-weather pad with a two-way adjustable valve that makes inflation, deflation, and micro-adjustments easier than ever. The soft, stretch-fabric top provides a cushioned yet very durable sleeping surface. This pad is a great choice for those seeking durability and supreme insulation in colder temps. For maximum insulation in cold weather, pair the Hinman with a closed cell foam pad.
