Light, With Cold Spots
I have used my Vesper 20 for several months now and for the most part, it does the job keeping me warm over 35 degrees. It is very lightweight and compresses down beautifully in my backpack. But if I hold it up to the light, even after a good shake, I see lots of blank spaces where down should be. I don't know if it is a characteristic of hydrophobic down to clump together like this, but it is disappointing, given how much I paid for it.

Excellent Ultralight Quilt
Compacts to 3L for Uber ultralight yet with a good pad its a great three season quilt and with extra layers and your puffy can allow you to survive a sudden early season snow storm. That’s versatility!

At First I Thought “How
At first I thought “how is this thing gonna be warm down to -6?” It’s incredibly light in the pack, compressing down to less than half the size of the sleeping bag it replaced. The first night in it I knew I made the right choice. My sleep system just lost almost 4 lbs with this and that new pad I bought. Cheers Thermarest for looking out for the old guys who got tired of packing all that weight around.

So Disappointed
It is nowhere near the temperature rating it claims. It isn’t even warm enough in the summer. And I run hot. So disappointed. I’m going to go back to my heavy old duck down sleeping bag that I have been using for decades. At least it kept me warm at 40°. I don’t even feel like I could responsibly sell this to anyone.

Regular Is Not Long Enough For A 6ft Person; Otherwise Good
Bought a Regular based on the incorrect description the manufacturer provides. I found it clearly incorrect in that with a pad in the quilt, it can momentarily stretch to cover my shoulders but will naturally relax to cover only my upper torso, not my shoulders. So, i bought a LONG which I'm about to test. Aside from the regular size being too short (unlike any sleeping bag I've ever bought), I like the bag. It is relatively light, the sleep system relying on a pad to insulate from the ground works, and the 900 fill down insulates well. I figure the quilt will be adequate down to at least the mid-30s (assuming I'm wearing cloths as these ratings do assume). Likely lower if I use a fleece liner and a thin bivy cover around the bag. But you'd better protect your pad if you camp in prickly areas in other than warm temps, as the system assumes the pad will keep you warm on the underside.
