About Marmot 20°F Sorcerer Sleeping Bag - Mummy

Closeouts. Marmot's 20°F Sorcerer sleeping bag is so lofty, you might just wonder if it's down. Overlapping waves of cozy Spirafil insulation eliminate cold spots and keep you warm, and the quality synthetic fill dries quickly when it gets wet.

I used it on a backpacking trip and on a car camping trip. It's comfortable and warm. Easy to stuff into its stuffsack, but the "latch" on the stuff sack cord doesn't seem to hold very well, tends to come loose. the zipper does get caught, so you just need to get the hang of how best to use it. ...

    Got this for the wife for Christmas for backpacking trips and couldn't be happier with it. She's about 5'8" and this size is perfect for her. I'm about 6'2" and tried it on after she opened it, and it fit me pretty good too tho a tad tight. For my size or larger I would definitely get the long. Obviously haven't used this in the elements yet so can't comment on temp rating, but Marmot is a very solid brand so I'm not too concerned that it won't hold up. Very happy with this purchase from STP!

    The bag is comfy, and looks durable. The only negative I could find is the bag. Will buy another one as the one that is provided does not compress the bag well.

    Very pleased and looking forward to using soon. Has plenty of room and I measure out at 6' 2".
    Bought the 6 foot bag and glad I did, used a tape measure and the inside of the bag was 73 inches. Happy I did not by the long version.
    Quality appears first rate especially for the price.

    Definitely worth the money. Deducted one star because the zipper catches very easily on the fabric and gets hung. Unzipping at night to wander off and pee can be a chore. But, the zipper tabs glow in the dark, so they're easy to find.

    I just returned from a fly fishing guide certification in Alcova Wyoming on 5/19. We camped on the Grey Reef on an exposed bluff above the river...
    We had a major spring snow storm! Temps in the 20s and high winds and snow. My new Marmot Sorcerer was up to the task!
    The first 2 nights I slept very comfortably in my boxers. The third was the coldest and I slept in my long underwear and was cozy all night! Love the glow in the dark zipper pull :)

About Marmot

Conceived in a university dorm room by a pair of climbing buddies, Marmot Mountain Works first opened its doors in the spring of 1974 in Grand Junction, Colorado. At the time, the base of operations was a 100-year-old stone building. That same year, the first Marmot down jacket was produced specifically for an action flick called “The Eiger Sanction,” starring legendary actor Clint Eastwood. In the four decades since, Marmot has continued to engineer reliable gear that exceeds the expectations of outdoor athletes. Today, Marmot tents, backpacks, outerwear, clothing and Marmot sleeping bags are still pushing the limits in the planet’s most challenging conditions, from the summits of the world’s highest mountains to the deepest river basins.
