Why We Like The Marmot Lithium Sleeping Bag

Marmot designed its Lithium Sleeping Bag to deliver exceptional warmth and comfort, so we can spend restful nights in the alpine. Weighing less than three pounds and filled with light, compressible down, this bag saves weight and space in our pack, while the curved, stretchy baffles make sure their lofty fill doesn't shift, eliminating cold spots.

Excellent

[This review was collected as part of a promotion.] Replaced my old marmot bag with this one after many years of service. Short bag is great for my height 5' 5". Bag dries quickly from tent condensation. Zipper design keeps bag from getting caught - nice when adjusting for warmth in middle of night.

Very light, compressible, and warm

Lithium is one of the lightest solid elements on the periodic table, which explains why Marmot chose that name for this 0-degree F bag. This bag is made up of 800-fill hydrophobic down and a very thin face fabric in order to give it incredible lightness and compressibility. But to keep the bag light, Marmot opted to use a smaller draft collar and draft tube than you may find on some other 0-degree F bags, which reduces it's cold-temperature ability some. "Winter" has only just begun in the Adirondacks, so I took this bag and my two-person summer tent on a recent 2-night backcountry camping trip. I was able to fit everything into a 58L pack, and my total pack weight was only about 27 pounds with water and food. I hiked 2.5 miles and 1200 ft elevation gain to my campsite, and pitched my tent on about 3 inches of snow and ice. My sleep system was my Lithium 0-degree F bag, XTherm sleeping pad, and Aeros pillow. I did not use a bag liner. Inside the bag I only wore my hooded baselayer top at night (no bottoms or socks), and I did not use any heat packs or hot water bottles. The outside temperature began around 25 degrees F and got down to about 15 degrees F at night. The bag performed very well. I did not feel cold in my core or lower body. There was some heat escaping from my chest area, probably due to the minuscule draft collar, but it wasn't bad once I zipped the bag all the way up and cinched the hood. The anti-snag zipper worked great, but the inside pocket is basically useless. In the morning, I noticed the typical wetness near the face opening of the bag from breathing/condensation, but it quickly dried out. The bag never felt like it was holding excessive moisture. Overall, I was very happy with the bag. I think this bag's advertised 0-degree F rating might be possible with thermal weight baselayers and a bag liner, but this bag is ideal for temps above 10-degrees F.
