There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars).

I like completely sewn bottom & footbox because I sleep super cold. This open quilt is great for people who sleep warm and want the option to vent (I never do below 60!) From my research on EE quilts, it seems like EEs 20 quilt should roughly correspond to an EN *comfort* (aka womens) rating of 30, and 21? For lower limit (men's). That would be with wearing base layers and a down balaclava, which is basically a substitute for a sleeping bag hood.
Something is definitely wrong if you are shivering at 50 in a 20 degree quilt. (Assuming you normally find bag temps accurate. I always add 15F to rating because I sleep cold) I would inspect the quilt to make sure you have down in all the baffles. If all is well there, then post on backpackinglight etc for feedback on your sleep system. Good luck! Shivering is no fun!!
