The Marmot CWM -40 Degree sleeping bag has been field tested in extreme conditions all across the globe. It offers a host of cold-weather attributes including high-fill-power down, a waterproof/breathable shell, draft-stopping features, and a high-tech hood.
The bag is insulated with lofty Responsible Down Standard-certified 800 fill power goose down which delivers maximum warmth and compressibility. A waterproof/breathable PertexShield 30D ripstop nylon shell gives you and the insulation durable protection while Pertex Microlight 30D ripstop nylon on the interior provides next-to-skin comfort.
When down insulation moves around too much you can end up with "dead" spots that diminish thermal efficiency. The bag's stretchy, strategically-oriented "cross-baffle" construction prevents this movement so you can enjoy consistent, reliable warmth. The side seams have been moved to ground level to minimize
heat rising and being lost through the seams. Inside, a draft tube prevents cold air from slipping through the zipper.
Other features include a baffled insulated hood, a down-filled draft collar, and a baffled footbox with wrap-around construction and a reinforced lining, zipper guards, and a hidden draft tube pocket. Both a stuff sack and a storage sack are included.
The Marmot CWM -40 Degree sleeping bag is available in your choice of Regular (fits up to 6') and Long (up to 6' 6") size options.
