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. ...

    This bag is fine for an overnight sleepover or car camping. Definitely not recommended for backpacking. Too heavy and bulky.

    Marmot makes the best sleeping bags in my opinion. I have had multiple brands through the years and Marmot always is true to their heritage.

    Bought this bag for weekend hiking trips in the Fall & Winter in North Georgia. Used it last weekend and the temperature dropped to about 39 degrees. Never felt any cold inside this bag and slept with the top not fully zipped shut. I did buy a separate Alps Compression sack to use with it as the stuff sack it comes with is ok, but not really suitable for back packing.

    I got this bag in August and went camping but it was about 60 degrees at night so I didn't get to put it to the test. It is well made and I think will serve me well for my light duty needs. It was plenty long for a 5 foot 2 inch woman of medium to small build. I thought the shoulder chest area felt a bit snug but it is a mummy bag after all. I might have been better off with the woman's version of the bag. I am happy and would recommend it to others.

    Just had this bag on a 4 day trip in the Sierras and it worked well. Was warm enough though it didn't get any where near the 20° rating. Reasonable weight. The stuff size could be a little smaller but it is still well within reason.

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.
