Marmot has gone above and beyond again with the Lithium EQ Sleeping Bag. With the same construction as their Lithium bag, the EQ has MemBrain, a waterproof/breathable fabric.


For sleeping in rapidly changing mountain conditions in temperatures down to 0deg F, this is our lightest, most durable offering.
