Comfort in the coldest places.
Marmot designed its Lithium 0-Degree Down Sleeping bag to deliver exceptional warmth and comfort, so you can spend restful nights in the alpine. The Lithium is part of Marmot's ultralight lineup, weighing just over two pounds, and 800-fill down gives it the compressibility needed to be a viable option during those more gear-intensive backcountry missions where every inch of pack space must be carefully considered.
The Lithium features newly redesigned baffle construction that uses a curved shape to help keep the water-resistant 800-fill down from wandering throughout the night. The foot box is anatomically shaped to give your toes some extra wiggle room and has a wrap-around construction to limit the amount of areas where heat can be lost as you sleep. Even though the down is coated with a Down Defender water-resistant coating, Marmot also used treated both the lining and Pertex Microlight face of the bag with a DWR finish for extra protection against moisture. Pertex Microlight fabric is also superlight and highly breathable, so it saves ounces and makes sure you don't sweat and wake up frozen in the middle of night.

This sleeping bag is perfect for cold nights in the backcountry. I love the mummy shape layout, keeping you covered up nicely while providing enough room for a comfortable night sleep. Well designed, with full length zippers, and extremely durable.

This bag is so well made and designed, warm and one of the lightest 0° bags I could find, coming in at 2 lb 10 oz. You can see the attention to details in every aspect of this bag. The main zipper operates smoothly with a generous zipper tab and no snags. There's a small short zipper on the opposite side of the main zipper, this allows me to sleep with my arms outside the bag give me more room inside. I'm a big guy at 5' 11" 240lb and I wear a size 48 jacket so it's a little snug when all zipped up inside in my shoulder area, other than that it's very roomy for mummy bag. They even thought of putting little pockets at the end of the zipper run to tuck the zipper into keep the zipper off of any skin and
creating less drafts. There's a nifty little storage pocket on the inside of the bag perfect for keeping your phone or wallet in. You can snug the hood right down to a little tiny slot. Even the stitching seems to have quality everywhere you look, special little reinforcing tacks at stress points. Had this bag out in -1° weather I was warm and slept like a baby. Last I'd like to say inside this bag is really soft! This is a nice bag I like this bag. 😃
Awesome sleeping bag!

I bought this for my son for Boy Scouts. We live in the North East. He recently camped out twice on two separate occasions in January and was very happy with the warmth of the bag. It got as low as 15 and he said he was totally warm. He is not a big kid. I am extremely happy with this bag and the customer service at Backcountry! Love it
