Quilts With the Most Down Loft Per Dollar
Almost no quilt maker publishes a lab temperature rating, so comparing quilts on their stated temperature means comparing marketing departments. What most of them do publish is fill power and fill weight, and multiplying those gives the volume of loft the down in the quilt can produce — the physical thing you are paying for. Dividing that by price ranks quilts on something checkable.
How this list is orderedRanked by loft budget (fill weight × fill power ÷ 1000) divided by approximate price, for down quilts that publish both figures. 9 entries qualify.

Enlightened Equipment
Enlightened Equipment Revelation 20
4.16k in³ per $100
1 lb 7.6 oz · ~$345 · Quilt
The quilt that made quilts mainstream in America. Enlightened Equipment builds every Revelation to order in Minnesota across five lengths, four widths, six temperature ratings, two fill powers and three shell deniers, which is thousands of combinations and the reason this entry lists one representative build rather than a size run. The Revelation's distinguishing feature against the otherwise-identical Enigma is a zippered and drawcord footbox that opens completely flat, so the same quilt covers a 20-degree night and a 60-degree one.

Therm-a-Rest
Therm-a-Rest Corus 20 Quilt
3.98k in³ per $100
1 lb 10 oz · ~$310 · Quilt
The Vesper's argument made in cheaper materials: same shape, same straps, same EN comfort rating of 32 °F, but 650-fill duck down inside a 20-denier shell instead of 900-fill goose down inside a 10. That costs seven ounces and saves $150, which for most weekend backpackers is the right side of the trade. The thicker shell is also more forgiving of the way quilts actually get used — dragged half-off the pad, sat on at breakfast, stuffed wet.

Katabatic Gear
Katabatic Flex 22 Quilt
3.20k in³ per $100
1 lb 7.9 oz · ~$409 · Quilt
Katabatic's pad-attachment system is the thing the rest of the quilt world copies, and the Flex is the model built around it: the quilt clips to two cords that run under the pad, and it can slide and roll with you while the edges stay sealed. That is the whole answer to the standard complaint about quilts. The Flex adds a zippered footbox to the formula so the same quilt opens flat into a blanket on a warm night, at the cost of an ounce or so over the sewn-footbox Alsek. Katabatic publishes single-side loft (2.75 inches here) and exact fill weights per size, but no lab rating.

Katabatic Gear
Katabatic Alsek 22 Quilt
3.16k in³ per $100
1 lb 7.3 oz · ~$409 · Quilt
Same temperature and nearly the same fill as the Flex 22, with a sewn footbox instead of a zipped one. That saves about six-tenths of an ounce and a litre and a half of packed volume, and removes the only moving part on the quilt. If you have never wanted to open a quilt flat — and most people who own one never do — the Alsek is the better of the two.

Zenbivy
Zenbivy Light Quilt 25
3.13k in³ per $100
1 lb 6 oz · ~$289 · Quilt
Zenbivy solved the quilt draft problem differently from everyone else: instead of strapping the quilt to the pad, the quilt clips to a fitted sheet that is already on the pad, so the seal moves with you and there is a hood-like head end built into the sheet. It is the most bed-like sleep system in this catalogue. Zenbivy publishes a limit-and-comfort pair of its own — 25 °F and 35 °F for this model — but does not claim ISO testing, so treat those as the maker's figures rather than lab ones.

Katabatic Gear
Katabatic Palisade 30 Quilt
2.62k in³ per $100
1 lb 3.8 oz · ~$389 · Quilt
Katabatic's three-season quilt, and the one most of its customers should probably buy: 30 °F, a sewn differential-cut footbox, 19.8 ounces and a 4.5-litre packed size. The footbox is closed rather than zippered, which is lighter, warmer and smaller-packing than the Flex — the price is that it cannot become a blanket. For summer and shoulder-season trips in the mountain west it is the quilt that shows up most often on gear lists, and the loft figure (2.25 inches per side) is published so the rating has something behind it.

Zpacks
Zpacks Solo Quilt 20F
2.52k in³ per $100
1 lb 2.3 oz · ~$489 · Quilt
The Classic bag with the hood and the back panel removed — the same down weight, the same 900-fill, half an ounce lighter. That half-ounce difference is the most useful single data point on this whole site about what a hood actually costs, and the answer is: almost nothing, because the down that would be under your back has already been left out of the bag. What you are really choosing between is a hood and a draft-free back, versus the freedom to stick a leg out.

Feathered Friends
Feathered Friends Flicker UL 20 Quilt
2.50k in³ per $100
1 lb 9.5 oz · ~$559 · Quilt
The Flicker answers the quilt-versus-bag argument by refusing to pick: a full-length centre zip and a drawcord footbox mean it closes into a hoodless bag on a cold night, opens as a quilt on a mild one, and lies flat as a blanket in a hut. Because the zip runs down the middle rather than the side, the closure sits over your chest where you can reach it, and there are no pad straps to fight. Sixty-two inches of wrap width is generous, and 14.7 ounces of 950-fill down sits inside a 25.5-ounce total.

Therm-a-Rest
Therm-a-Rest Vesper 20 Quilt
2.45k in³ per $100
1 lb 3 oz · ~$460 · Quilt
Nineteen ounces, 900-fill goose down, a 10-denier shell and an EN comfort figure of 32 °F. The Vesper is one of the very few quilts from a mainstream brand that publishes a lab rating at all, and the number it publishes is worth reading carefully: a bag called a 20 that tests to a 32 °F comfort rating is a bag most people will feel cold in at 20. That is not a Therm-a-Rest problem, it is what the 20-degree label has always meant, and the Vesper is one of the few products honest enough to show its working. The SynergyLink straps are the good kind — they let the quilt float rather than pinning it flat.
