Toasty Warm Sleeping Bags

These sleeping bags kept my hubby and I warm whilst camping in Yellowstone. I get extra discount from here:


How much does the bag weigh?


Is there a size dimension chart?

Hey Eli, Marmot did not provide us with the specs when we posted the product page but i was able to find the length of the regular bag is 72 inches. Where there other dimensions you were looking for?




Can you tell me the fill weight and compressed volume of this bag? I am trying to compare it to the Marmot Helium, which looks to be similar in design with a fill power of 800 instead of 700.

Hi Dustin, The fill weight of this bag is 19.5oz/550grams. The compressed volume is 404.6ci/6.63 liters


What is the weight of this bag?

Hi David, The weight of this bag is 2lbs 4.5 oz. The fill weight is 19.5oz/550g


What's the comfortable temperature? What's the actual filling weight of down

I had called Marmot to double check these specs. It looks like the comfort rating is 21.4F and the weight of the bag is 2lbs 4.5oz. The exact fill of this back is 19.5oz/550g.
