This is our warmest expedition bag, 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, our 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.
