First up is a Marmot Lithium 0 degree mummy bag, 800fp down, regular/regular left side zip. Purchased April 2018, used three nights, and always stored uncompressed in the pictured storage mesh bag in a closet. New these are going for about 500USD. Letting this go for $350, $325 for local pick up in the Bay Area.

Next up is a 2016 Marmot Never Summer 0 degree bag, regular/regular left side zip. This is basically a cheaper version of the Lithium, with 650 fp down instead of 800fp, and fewer "features". This bag has seen more nights of use, about 15 overall, and is being sold as is. That said, there is absolutely nothing wrong with the bag - not leaking down, zippers functional, stitching is all intact, no smells, etc, so a good wash with down specific wash and a thorough drying and it'll be good as new. Selling for $115, $95 local pick up in Bay Area.

Reason I'm selling - I've transitioned to quilts, even in winter. No need for these anymore so time to free up the space!

A note on Marmot temperature ratings: Marmot (and retailers like Backcountry and REI) list these zero degree bags. But if you look closely (see photos), you will see that 0 degrees F is the LOWER limit EN rating, not a comfort rating. These are NOT Feathered Friends or Western Mountaineering type comfort ratings. That said, I have found them true to their (comfort) rating. I have not taken them much below 20 degrees however, and as always temperature ratings for sleep systems are highly subjective and conditional on factors such as evening meals, etc, etc, yada yada. You know the drill.
