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