This winter sleeping bag called Spirit CCS from the Czech outdoor equipment manufacturer Pinguin will be appreciated by anyone 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 has been used. The designation "CCS" tells us that the outer layer additionally uses Clima Control Shield technology, which prevents unwanted heat loss while ensuring balanced breathability of the sleeping bag.
All Pinguin sleeping bags use proven YKK zips, which can be closed from both the inside and outside. On the inside they are backed with a flap that prevents drafts. And if you own a second sleeping bag Spirit, Micra or Topas with the opposite zipper, you can join them together.
