I'm selling my Marmot CWM -40° sleeping bag. Is that -40°F or -40°C you ask? It doesn't matter - this is so cold that those are the same temperature!
This bag is brand new (still has all the original tags attached, never used, never even taken outside) and has been stored for the couple years I've had it in the nice mesh bag it comes with so the down filling (800 fill power goose down) should be in excellent condition still. This is an extra-long model with a zipper on the left side. It should work well for people about 6ft or taller (I am 6'1"). The original storage bag and compression sack are included.
I don't think this exact model is made any more, but you can still see the specs on Amazon: https://www.amazon.ca/Marmot-Membrain-Down-Sleeping-Right/dp/B00M824QU8 (note - that says right-side zipper; mine is on the left side).
I originally purchased this for a climbing expedition which ended up getting canceled, and I've since lost interest in doing anything extreme enough to require this bag.
If you live nearby, I may be able to deliver for free - feel free to ask. I also make it over to Oakland and sometimes Berkeley on occasion so if you're willing to wait a bit I might be able to get over there too. I prefer PayPall/Venmo/Zelle, but can also take cash if needed.
Price is firm! Any messages that attempt to negotiate the price will be ignored.
