This winter sleeping bag called Spirit CCS from the Czech manufacturer of outdoor equipment Pinguin will be appreciated by everyone looking for a quality sleeping bag at a reasonable price.
The outer layer is made of water-resistant Ultralight DWR nylon (Durable Water Repellent technology), the inner layer is made of quick-drying Micropolyester, and in between, a three-layer thermal insulation layer with a shingle construction called BHB Micro has been used.The "CCS" designation tells us that the top layer also uses Clima Control Shield technology, which prevents unwanted heat from escaping out while ensuring the sleeping bag is balanced for breathability.
All Pinguin sleeping bags use proven YKK zippers that can be closed from the inside or outside. They are sealed on the inside with a flap to prevent blowing through. And if you own a second Spirit, Micra or Topas sleeping bag with the opposite zipper, you can merge them together.
