Here I thought down UQs packed smaller...I've just never bothered looking seriously at them because of the price. I had just used pads and sleeping bags for a long time, then discovered serious hammock camping, but haven't had the budget to go all in on gear I didn't see as absolutely essential. If the MMGUQ wasn't meeting my needs, I'm in a place now where I'd look into it. But haven't had the need thus far, so on I go merrily down the trail with my synthetics!

BTW, I did DIY a UQ for the purpose of going below freezing. I got the kit from RSBTR with 5 oz Climashield. It gets me well below freezing, but it's twice the size of my Shamu, so I don't carry it unless I absolutely have to.
