How to choose a puffer without regret
Fill power, down versus synthetic, baffles, budgets, care. Everything worth knowing before you spend a cent — and nothing you can't verify in the shop yourself.
The fill power scale
The one number every salesperson leads with. Here's what it actually means.
Decent
City use, mild winters. Bulky for the warmth you get.
Good
The standard for solid mainstream brands. Versatile.
Very good
Excellent warmth-to-weight ratio. The sweet spot.
Exceptional
Expedition and high altitude. Ultralight, very expensive.
The five things to master
Down or synthetic?
Down (goose or duck) offers the best warmth-to-weight ratio on earth. It's compressible, light, and lasts decades if properly cared for. Its weakness: when wet it collapses and stops insulating entirely. Synthetic fills (PrimaLoft, Thinsulate) are heavier and less compressible, but keep insulating when soaked, dry fast, and cost less. Simple rule: cold and dry climate → down. Wet and rainy climate → synthetic.
Fill power, decoded
Fill power is the volume one ounce of down occupies. The higher the number, the loftier the down — so the more warm air it traps for a given weight. An 850 isn't 'twice as warm' as a 425: it's equally warm at half the weight. It measures efficiency, not absolute warmth. The quantity of down in the jacket matters just as much.
The down-to-feather ratio
You'll often see 90/10 or 80/20. The first number is down (the small insulating clusters), the second is feathers (with quills, which add structure but insulate poorly). The higher the down percentage, the better. Below 70/30 the jacket will be heavy and lose its loft quickly.
Baffles: sewn-through or box?
Sewn-through baffles stitch straight through the jacket — that's the classic quilted look, but every seam is a cold bridge. Box baffles create internal chambers without piercing the outer fabric: much warmer, much more expensive. For city wear, sewn-through is plenty. For serious cold, insist on box construction.
Water resistance and DWR
Most puffers get a durable water repellent (DWR) finish that makes water bead up. That is not waterproofing: in real rain it saturates within minutes. If you live somewhere wet, look for a membrane (Gore-Tex, Pertex Shield) or hydrophobic treated down. And reactivate the DWR every season with the right spray.
By budget
A good puffer exists at every price. You just need to know what you're actually buying.
Under €120
Entry levelUniqlo, Decathlon, Zara, H&M
The Uniqlo Ultra Light Down is a genuine outlier here — unbeatable value in this bracket. Elsewhere, expect decent synthetic or low fill power down. Expect one to three seasons of life.
€120–350
The sweet spotPatagonia, Columbia, Pyrenex, Rains, Arket
This is where value peaks. 650–750 fill power, serious finishing, real warranties. A Patagonia Down Sweater at this price will last you ten years if you don't abuse it.
€350–800
The investmentArc'teryx, Canada Goose, Save The Duck Premium, Nanushka
High fill power down, box baffles, technical membranes or designer cuts. This is the tier where you simply stop being cold and the jacket becomes something you keep.
€800+
LuxuryMoncler, Prada, Bottega Veneta, Brunello Cucinelli
You're buying design, a signature, a status. Thermal performance is no longer the headline argument — but the finishing and the drape are from another world. Classic Moncler holds value well secondhand.
Care
A well-kept puffer lasts fifteen years. A badly kept one lasts two.
Wash it rarely — twice a season maximum. Down hates soapy water.
Machine wash at 30°C on a delicate cycle with down-specific detergent (never fabric softener, it mats the clusters).
The tumble dryer is MANDATORY, on low heat, with 2–3 tennis balls to break up the clumps of down.
Store it on a hanger, never compressed in a stuff sack — down permanently loses loft when crushed.
Small tear? Patch it immediately with something like Tenacious Tape, before the down escapes.
Classic mistakes
Looking only at fill power and ignoring fill weight. An 850 with 80g of down is colder than a 650 with 250g.
Sizing up 'to fit a jumper underneath'. An oversized puffer lets cold air circulate and loses its efficiency.
Washing a down jacket without tumble drying it. Wet down that air-dries clumps permanently and never lofts again.
Buying down for a rainy climate. Soaked down stops insulating completely — synthetic doesn't.
Ignoring the RDS (Responsible Down Standard) certification. It guarantees the down didn't come from live plucking or force-feeding.
Keeping the jacket compressed in a stuff sack year-round. It's the fastest way to kill it in two years.
