The JUNGLEBOA sleeping bags are made with Elevation Insulation. The sleeping bag uses a 2-layer offset construction, sometimes called a "bag within a bag." The contoured hood and mummy shape helps seal up your warmth and keep you warmer. The JUNGLEBOA is a great backpacking sleeping bag to take along on your hikes that won't take up all the space in your pack.
