Rock & Ice 2008 Gear Guide Couloir:

In the 1970’s, Eric Reynolds and Marmot changed the industry. They made a better sleeping bag using higher lofting down, and others followed. The Couloir maintains that legacy. One tester, a professional mountaineer called the Couloir a classic bag, “warm with comfortable dimensions, not too tight or too wide, a great hood, an efficient collar and raised warm foot section.” We all agreed.
Pros: Conservative rating. Great price. Warm hood/collar combo. Very warm. Comfortable raised foot. Good warmth-to-weight ratio.
Cons: None
- Larry Amkraut

Must have. Marmot stuffs high-loft down into this zero-degree sack, then adds smartly placed drawcords and extra baffles so you can seal in the warmth. At three pounds, three ounces, you’ll barely notice it in your pack.
