Temp rating for two person quilt for sierras

I got a Zpacks twin last year for a trip to Colorado and future adventures with my fav woman. I opted for the 20*. At 40*, we laid it out like a blanket all night. At around 30*, we had on Cap 4 tops and Cap 3 bottoms while spooning for extra warmth all night. We took it down to 22 degrees on NYE this year on the AT wearing Cap 4 tops and Cap 3 bottoms along with down hooded jackets. I was happy and she was cold.

All in all, I'm glad I got the 20* for her since we typically hike with lows in the 30s plus I am typically a cold sleeper. The only problem I have with the twin quilt is the opening we can create at our heads in between us. We both toss and turn all night and had to learn how to not let a draft in by our shoulder/heads. Not a big deal at 35-40*, but immense at 22*. Besides that one issue that is manageable, I love the quilt and the weight savings for both of us.

For the temp you want an the amount of down, the EE Acomplice seems to be closer to what you are after?

3 ounces more down with the 20*.
It's also a better size and takes care of the draft between the heads problem.
It's $32 more but it's a rated 20* vs 30* with added fill.

I wanted to be able to squeeze an additional ten degrees (F) of warmth out of my primary lightweight sleeping bag. So, I did a DIY down blanket using the sheerest of nylon fabric and a few ounces of goose down. On a cold night, I put that over me within the sleeping bag. On a cold morning, I get up and use it as a down kilt until I break camp. If the weather is going to be warm, I leave the down blanket at home. I think the whole thing was about four ounces.

Bob you sound like you're describing something like Montbells down blanket: http://www.montbell.us/products/disp.php?p_id=1124439

My husband and I tried a 2-person 30F quilt : He's a warm sleeper, and he was perfectly comfortable to about 35F. Although I wore warm base layers, I was cold because every time one of us moved, cold air drafts entered around the neckline of the quilt — even spooning didn't stop that from happening. So, while the quilt itself was "warm enough", the cold air coming in multiple times all night long ruined it for me.

Now we're back to individual sleeping bags. YMMV.

Thankyou for the responses. I like the EE Accomplice but was told by an rmoyye that the footbox has to be seen due to its design. I like a relevation style foot box for the flexibility. So I'm still looking at the underground quilt with extra fill. Maybe get can add a snap or too at the top to minimize drafts coming in?

We don't do the drawcord style footbox on these because with the foot so wide it just doesn't seal well. Will Newton had us make one with the drawcord, we didn't like it for its inability to seal tightly but you could ask Will about it.

We got a zpacks 20 degree double quilt and we've had good results with it. The times we had it in the twenties we were cold though. Of course we both had our base layers on. Sometimes we will put on the puffies to help with the draft. She typically will have to put on all the layers she has to sleep comfortably in the low twenties. The closure at the top helps and if all else fails we just pull our heads under and cinch up the top.
The weight savings is awesome. We take a big weight penalty when using our hammocks. Being able to share body heat is pretty awesome too. In our minds if you are a couple, and sleeping on the ground, there is no reason to consider anything else (she might have some sort of gas argument). I guess the only thing I really don't like about it is the pertex material. It makes any bare skin that I have touching it sweat, even if it's cold. I prefer the argon material in this regard.
I haven't compared the amount of down between the two but I'd like a little bit more down to take it into the low twenties.

Thank you for all the replies.

Tim can you make the enigma with a zippered foot box were the sewn foot box would be? Same everything but zippered instead of sewn? I really like the idea of an open foot box over sewn. I understand the drawcord may let in a lot of drafts. What about a zipper?

I'd love to say yes, but we are turning down almost all custom requests as we have so many orders to build. Custom work really slows everything down more than we can afford right now.
