Marmot Lithium

I recently purchased this bag and was confused when I saw the tiny stuff sack they sent along with it. I didn't think there was any way I could get that huge fluffy bag into that small of a pouch, but lo and behold, it fits. I immediately loved how little it weighed and how small it compressed leaving me lots of room for my other gear. I took it out last week for it's "maiden voyage" in the High Uintas where it dropped down to 31 degrees at night. I tend to get cold easily but I slept very comfortably and had to unzip the zipper a bit because I got a little too warm. I paired this with REI's Trailbreak sleeping pad and am very happy with my setup. Would highly recommend this bag. I'm 5'3" and had tons of leg room.

Before I got this bag I had been using hand-me-down bags from friends or family, and I must say I am BLOWN AWAY with how warm and comfortable this bag is. The down is perfect for those icy nights and the extra zippers make this bag suitable for sleeping in moderate temperatures as well. I especially like the zipper pocket that I've used to keep batteries and stove fuel canisters warm at night, and the extra thick insulation at the feet is a huge plus given that I've always woken up with freezing feet while camping until this bag came along. Would absolutely recommend.

For years I had been using a synthetic fill 15 degree sleeping bag for my summer backpacking trips. I'm a cold sleeper, but even on nights when the temperatures only went down to 40 degrees or so I would still wake up in the early morning chilled to the bone with frozen feet, even while wearing two layers of wool socks! Well, thanks to this sleeping bag, those days are all in the past. The down fill is far superior in my opinion: more comfortable, more breathable, and more effective at insulating. The down continued to perform perfectly even when the outside of the bag was covered in condensation. The zero degree rating works perfectly for me, even when the temperatures aren't too low. I never overheat in this bag, but I also have never been cold - just a perfectly comfortable temperature all night long, and waking up to happy feet. Thanks Marmot!

For spring overnight ski tours in the Cascade mnts of Wa. the bag kept me warm. I’m a petite female who likes to have a warm bag and this one did the trick. Thanks Marmot!

The Marmot Lithium is a bag for those who bivy less or if going lightweight is a higher priority. Overall, the Lithium is one of the warmest we tested in our Cold Weather Down Sleeping Bag Review, even without a dedicated neck baffle. It is not the most weather-resistant. We feel this bag is a great match for a backpacker who likes to use a lightweight waterproof shelter. This way you can enjoy the weight savings without worrying about getting wet.
