A very good deal on a down bag. I think it is not quite a true 20 degree bag, but still mine has served me well in Alaska shoulder seasons and south east AK.
Looks like a good deal, not sure about the site though. I'd be curious to see if anyone else has ordered from the site, only because it might be spoofed. No contact phone numbers, plus the Facebook, IG, and Twitter link are all broken. The 'contact email' button goes to your@email. When entering the item number into Google, it certainly does not reflect the Marmot bag. Red flag for sure. Buyer beware.
Marmot's official link is below. Screenshot of the 'contact email' is also below.
