This winter sleeping bag named 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 “CCS” designation 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 the inside as well as from the outside. On the inside they are backed with a draft tube to prevent cold air from getting through. And if you own a second Spirit, Micra, or Topas sleeping bag with a zip on the opposite side, you can join them together.
