When staying in a non-climate-controlled environment, sleeping bags and mummy bags are vital assets. Sleeping bags work to regulate body temperature in the frigid cold on a mountainside, or help you sleep comfortably in a house with no power. Sleeping bags have a variety of comfort ratings you can follow to master each temperature situation. All sleeping bags offer invaluable protection and comfort when checking in with nature. Mummy sleeping bags, noted for tapered shape that restricts movement, are popular within the backpacking community for their incredible lightweight and considerable warmth. Mummy sleeping bags are ideal at high altitudes and in extreme cold situations. Sleeping bags are heavier than mummy sleeping bags and may not be as good to use as backpacking sleeping bags and are ideal for warmer temperatures. Sleeping bags from Marmot, Kelty, Sierra Designs offer quality builds and rated insulation, so you sleep well no matter where you set up camp for the night.
