Reviews & Ratings for Marmot Lithium Sleeping Bag — 21 reviews — Page 1

So I’ve loved this bag in 20-30 degree weather and up. It’s so incredibly light weight, warm and cozy. Definitely a snug fit, but that’s to be expected. I would say it’s pretty chilly below 20 degrees though, although the comfort rating is 9. The zipper did break on me after about 30 nights sleep, but I work in a super sandy environment and pretty much every sleeping bag I’ve used out there has had the zipper break at some point

I live in the PNW. I needed a bag that I could use for emergencies and backpacking. I have no problem fitting into this bag. I have enough room to zip up all the way. It's snug and yet I'm able to move inside easily. Since the virus I've been using it indoors with the windows open. Most night it's been around 35° to 45°F. The thing I most like is I don't get overly heated. When you get out of the bag you sure can tell the temperature differences.

I tested the Lithium against the Marmot Never Summer for my early and late season tent camping needs supporting trail work events. I already owned a Nemo Nocturne 15. I hadn't tested that one to determine how close to 15 degrees it would go and learned the hard way that its threshold was closer to 30 after two weekend uses in Wyoming and Colorado. In my test of the Lithium and Never Summer, the Lithium was superb and warranted the higher price point. For the test, I used my Big Agnes 3 season tent and Exped Downmat UL Winter pad, and wore Smartwool 250 baselayer and Darn Tough socks. At 12 degrees with 25+ MPH winds, I slept well with no drafts through the zippers (right and left side), hood, and draft collars. Around 0200, I was so warm I shed the socks and unsynched the torso draft collar. Great bag. Will test the upper temperature limits in the spring/early summer. Definitely recommend.

Very happy good zipper thick and light bag ,only used one weekend in below zero Celsius and I was warm as toast.

Warm and cozy.

Should have a draft tube collar, but it's roomier compared to the comparable Mtn Hardware Phantom and has better loft. Never slept in the latter so no other comparison.
I was good (a cold sleeper) at 10 degrees in Sequoia snow (but I had inadequate mat)

shipping was extremely fast and the bag was well package. Super light bag that I'm looking forward to putting to the test this fall in the mountains of northern BC.

Fantastic sleeping bag.
It's worth of money.
I will recommend this to my friends who they are seeking winter sleeping bag.

Very warm and lightweight, packs really samll. Combinet with Neoair Xtherm is perfect for any winter/high altitude conditions. May be too warm for winter camping. Quality product!
