Therm-a-Rest Vesper 32F Ultralite Quilt vs Enlightened Equipment Enigma 20

Both are 20°F down quilts for backpackers who want to cut weight and sleep without a mummy bag's confinement. The Vesper 32F is lighter and uses higher-fill 900 down, and owners consistently call it warm for its weight and roomy to move in. The Enigma 20 carries more down (15.5 oz of 850-fill) and comes in more sizes, including wide and long-wide, which suits cold sleepers and bigger frames. Pick the Vesper for the lowest packed weight and a pad-strapped system; pick the Enigma for more down, more size options and a sewn footbox.

  • Choose the Therm-a-Rest Vesper 32F if you count grams, want 900-fill down and a quilt that straps to your pad, and you sleep on a standard-width pad.
  • Choose the Enlightened Equipment Enigma 20 if you sleep cold, need a wide or long-wide size, or want a sewn-closed footbox and more down for the rating.

What reviewers say

Therm-a-Rest Vesper 32F Ultralite Quilt

  • 4.5 / 536 ratings

Owners rate it highly for warmth-to-weight, small packed size and freedom of movement compared with mummy bags. Complaints center on long-term durability: down migrating between chambers and leaking, plus straps that don't seal the sides well.

What people mention
  • WarmthPraisedOwners say it is very warm for its weight and comfortable down to about 32F.
  • Pack sizePraisedReviewers note it compresses to a very small packed size.
  • Down migrationCriticisedOne long-term owner found about 8 baffled chambers empty of down after roughly 4 years.
  • Down leakageCriticisedBuyers report the quilt bled down without any visible holes.

Enlightened Equipment Enigma 20

Owners rate the Enigma 20 highly for its warmth-to-weight ratio and the draft-free sewn footbox. Most say the 20°F rating holds around freezing with a baselayer, and many praise the sizing range. Complaints center on the lack of a hood and the quilt sliding off unstrapped pads.

What people mention
  • WarmthPraisedOwners say it sleeps warm to around freezing with a baselayer.
  • WeightPraisedReviewers call it among the lightest 20°F options they have used.
  • FootboxPraisedThe sewn-closed footbox keeps feet draft-free, which cold sleepers single out.
  • Pad attachmentCriticisedSeveral owners say the quilt slips off pads that lack straps or clips.

Questions and answers

Which is warmer, the Vesper 32F or the Enigma 20?
Both are rated to 20°F, but the Enigma carries more down (15.5 oz of 850-fill) and is the safer pick for cold sleepers. The Vesper's 900-fill down is more efficient per ounce, so it is warm for its weight but has less margin.
Which one is lighter to carry?
The Vesper, at about 0.55 kg. The Enigma 20 is listed at 1 lb 4.9 oz. The gap comes mostly from the Enigma's larger down load.
Which is better for side sleepers and broad shoulders?
The Enigma. Its half-taper design leaves extra room, and it comes in wide and long-wide sizes. The Vesper has a tight, fairly narrow cut.
Do I need pad straps with these quilts?
The Vesper includes removable SynergyLink connectors that strap it to your pad, though owners say they fit poorly on 25-inch pads. The Enigma has no pad straps, so it can shift during the night.
Which lasts longer?
The Enigma's sewn footbox has no closure to wear out, and it draws fewer long-term complaints. Some Vesper owners report down migrating between baffles and down loss after about four years.
Is the Vesper worth stepping up to over the Enigma?
Step up to the Vesper if saving weight and packing small matter most and you sleep on a standard-width pad. Stay with the Enigma if you want more down, more size choices and a roomier cut.
