Months of hard use - Marmot Lithium Sleeping Bag

I've been using this bag for 2 years now and I don't have a single bad thing to say about it. Most notably I took this bag on a month long road trip from southern California up through Olympic and into Yellowstone during November. Temperatures dropped to the single digits many nights but I had no worries that this bag was going to keep me warm. Packs down to reasonable size (highly recommend using sea-to-summit eVent bag) and is lightweight for the amount of warmth you’re getting (expected at 850 fill down). After hundreds of compression, many a wet night, dirt and grime, this bag continues to deliver. Go-to bag for any trip where I’m expecting temps sub 40F all the way down to the singles.
