Marmot Lithium Sleeping Bag
I am psyched that winter is on its way, so I can start using the Marmot Lithium Sleeping Bag again. Before I received this sack, I had been using a negative 20-degree option lined with a waterproof shell, from a leading competitor. When I first tried the Lithium from Marmot, I was amazed at how warm it kept me, at almost 2 pounds less in weight.
