This is the warmest expedition bag from The North Fache, and it’s designed to venture into the coldest places on earth. Tested by world-class athletes to ensure maximum support and dependability, this updated version is roomier and more easy to access than ever before. Lofty 800 fill ProDown keeps you consistently warm down to a staggering minus 40 degrees Celsius. This is, in fact, ist the The North Face warmest down sleeping bag. A full draft collar and hood cinch cord help lock in additional warmth, while water-resistant Neovent Air fabric on the hood, footbox and back keeps moisture build-up at bay. A generous cut allows you to wear extra layers on the coldest nights, while the centre zipper makes getting in and out just that little bit easier.
