I'm one inch taller than your gf.  I bought a big agnes women's anthracite 20F, it's for max user height 5'6", it feels like the perfect size tbh. Other 5'6'' sleeping bags I found when searching were: - Nemo Forte Women's 35F - Nemo Tempo Women's 35F or 20F - Big Agnes women's Anthracite 30F Decathlon makes one (or more?) that comes in a smaller size for users of max height 5'3''.  E.g. Decathlon Simond MT500 Trekking Sleeping Bag These are synthetic bags, but I assume the down equivalents are probably similarly sized

You don't buy a Coleman sleeping bag. There are plenty of bags out there, even inexpensive ones, that are warm and pack down small. [This one](https://www.rei.com/product/216102/big-agnes-anthracite-20-sleeping-bag-mens) compresses down to 7.4L and is $105. That's fork bag size.

This is a solid bag. My Scouts have it and like it.

It was the Big Anges Anthracite 20° synthetic sleeping bag. Not currently on sale but I think it's still great value.

I will test my Anthracite 20 this weekend, temps are predicted to go down to 32, so right on the comfort rating. Will report how it went! I got it new for just 70€, if this thing works well at that temp it was well invested money!

Happy to report it went really well. Temps went not as far down as predicted, "only" down to 36F, but I was pretty toasty, couldnt even close the hood , otherwise it was too warm for me. Used a R4.2 sleeping pad and was wearing long base layers as well as Merino wool socks and hat. Very confident this would keep me warm even down to 32 or a few degrees below.

I have a Big Agnes single I LOVE so I’m jealous of all the folks here with the double. We have a flatlands fleece double bag and the Klymit double pad because they were the easy buttons through our wedding registry. The bag packs large for my taste but the pad is perfect. We sleep on top of each other at home and love snuggling all the same in the wild. Unless your trips are all ultralight backpacking, it’s quite cozy and romantic!

I would go with a quilt, they are great for moving around. Zenbivy is most peoples favorite, I really enjoy my Big Agnes.
