The North Face Inferno -40 Sleeping Bag Regular -
The The North Face Inferno -40 Sleeping Bag is designed for the most extreme environments from high-up in the Himalaya to down in Antarctica.
Made with ultra-light yet waterproof 20D Pertex Endurance fabric to insure the goose down, and you, stay warm and dry (seems not sealed, so not completely waterproof)
850 fill power goose down (one ounce fills 850 cubic inches!) is some of the lightest and most compressible down on the market.
Side-block chevron baffles keep down from shifting and creating cold spots, so you stay warmer.
Part of The North Face's elite Summit Series.
A Vaulted footbox is designed to fit around your feet and keep them extra warm.
An expedition fit is designed for layering while still being thermally efficient.
Comes with a compression stuffsack that doubles as an ultralight summit pack for when you're leaving camp behind for a fast and light push for the top.
Stay warm in the most extreme environments with this incredible expedition sleeping bag from The North Face.
