# How to Grade Down Fill Loss on Used Puffer Jackets: The Squeeze Test and Baffle Check

_By GradeThread Team · Published October 14, 2026_

> Fill loss decides the grade on a used puffer. Here is the squeeze test, baffle check, and zipper test that place it in Excellent, Very Good, Good, or Fair.

To grade down fill loss on a used puffer jacket, squeeze each baffle, check for empty or clumped chambers, and test the zipper, then score what you find under Structural Integrity and Functional Elements. Even loft with sound baffles and a smooth zipper supports Excellent or Very Good. Bare baffles, heavy clumping, or a failed zipper pull it to Good or Fair.

Here is the scenario we see often. A seller lists a puffer as Excellent because the shell is clean and the tags are crisp. The buyer opens the box, the shoulders are thin, and the chest feels like a sleeping bag with the stuffing shifted to the hem. Return requested, item described as not as described. The shell was fine. The insulation was not. This guide gives you a repeatable way to check, and a clear place to put each finding on the 1.0 to 10.0 scale.

## Why fill loss is a grading problem, not a cosmetic one

A puffer exists to trap warm air. When fill migrates, compresses, or leaks, the garment does less of its job. That is a function problem first and a looks problem second, which is why a puffer with a spotless shell can still grade lower than a scuffed one with full loft.

On the GradeThread scale, fill loss touches several of the five factors:

- **Structural Integrity:** baffle seams, stitch-through failures, and torn chambers.
- **Fabric Condition:** shell thinning, down leakage through the fabric, and abrasion that lets feathers poke out.
- **Functional Elements:** zipper, snaps, storm flap, and cuffs that hold heat in.
- **Cosmetic Appearance:** shiny patches, scuffs, and uneven puffing that shows from across a room.
- **Odor & Cleanliness:** damp-down smell, smoke, and body oil in the collar.

Marketplaces make this worse. eBay's condition field gives you only a handful of options, and Poshmark has no condition grade beyond NWT and a free-text description. Buyers fill the gap with their own expectations. A defined grade and a stated fill finding close that gap.

## What you need before you start

You do not need special gear. A flat table, bright side light, and a few minutes per jacket are enough.

- Daylight or a bright lamp held at a low angle to the shell
- A dark towel to lay the jacket on, so escaped feathers show
- A tape measure for loft comparison
- A lint roller, to check for quills on the surface

Zip the jacket fully and lay it flat before you touch it. Note how it sits. Pronounced flat bands across the chest or arms are the first clue that the fill has moved.

## The squeeze test and baffle check, step by step

Run these steps in order. Each finding feeds the grade at the end.

1. **Lay the jacket flat and look first.** Compare left and right sides, and chest to hem. Note any baffle that looks collapsed or visibly thinner than its neighbors.
2. **Squeeze each baffle between thumb and fingers.** Work top to bottom on the torso, then each sleeve. A healthy baffle feels springy and even. A thin one feels like two layers of nylon with a few feathers between them.
3. **Check for clumping.** Run your fingers along the baffle. Hard, ropey knots mean the down has been wet and dried badly. A few soft clusters are normal. Dense lumps with empty gaps beside them are not.
4. **Do the recovery check.** Press a baffle flat with your palm for three seconds and release. Good fill rebounds within a couple of seconds. Slow or partial rebound points to compressed or broken-down fill.
5. **Inspect baffle seams under light.** Hold the jacket up and look through each seam. Open stitching, wide needle holes, or visible gaps mean the chamber can leak or shift.
6. **Check for quills and leakage.** Wipe the lint roller across the shell, then look at the towel. Several feathers or pinpoint down clusters on a clean towel mean the shell or seams are leaking.
7. **Test the zipper and closures.** Zip and unzip the full length three times. Look for slider drag, teeth that skip, tape that pulls away, and snaps that do not hold. Check the storm flap and cuff elastic.

### A note on the squeeze itself

Squeeze gently. Hard pinching can pop a weak seam and create the defect you are trying to grade. If a baffle feels suspicious, let the jacket tell you through light pressure and visual checks rather than force.

## Reading what you find: fill loss patterns

Where the loss sits matters more than how flat the jacket looks overall. A few patterns come up again and again.

| Finding | Likely cause | Factor it hits | Typical tier range |
| --- | --- | --- | --- |
| Even loft, springy recovery, no leakage | Normal light wear | None, or minor Cosmetic Appearance | Excellent to Very Good |
| Slight softness at the cuffs or hem, rest even | Normal compression over time | Structural Integrity (minor) | Very Good |
| Shifted fill, flat spots that fluff back with a shake | Storage or washing shift | Structural Integrity | Very Good to Good |
| Hard clumps, slow recovery | Wet fill dried poorly | Structural Integrity, Odor & Cleanliness | Good |
| Bare or empty baffles at shoulders or chest | Fill loss, seam leak, or tear | Structural Integrity, Fabric Condition | Fair |
| Active leaking through shell or seams | Worn fabric or failed stitching | Fabric Condition, Structural Integrity | Fair to Poor |

The ranges are a starting point, not a verdict. A strong brand does not rescue bare shoulders, and a plain brand does not lose a tier for a soft cuff.

## Where zipper and baffle failures land on the five-factor scale

Zippers are the second big grade mover on outerwear. A puffer that will not close is not a coat in practice, which makes it a Functional Elements problem with real weight.

- **Smooth zipper, all closures working:** no deduction. Stays in the Excellent or Very Good range if other factors agree.
- **Slight slider drag or a stiff snap:** a minor Functional Elements note. Usually Very Good.
- **Zipper skips teeth or needs a firm tug:** a real Functional Elements finding. Expect Good at best.
- **Tape separation, a slider that will not lock, or a missing pull:** a functional failure. Fair, and lower if the jacket will not close at all.

Baffle failure stacks on top. A torn chamber with leaking down is Structural Integrity and Fabric Condition at once, and the grade drops accordingly. If a repair has been made, say so. A neat patch on a sleeve is a disclosed repair. A hidden one is the kind of surprise that triggers a return.

## Puffer jacket Good vs Very Good: the deciding line

This is the call sellers get wrong most often, because the two tiers can look identical in a flat photo.

**Very Good** means light wear with function intact. Loft is full or nearly so. Baffles recover quickly. The zipper runs clean. You might find minor shell scuffs or slightly softer cuffs, and a buyer could wear it this winter without a second thought.

**Good** means visible wear that affects the experience, but the jacket still works. You might see shifted fill that does not fully recover, a few lightly clumped baffles, a zipper that needs coaxing, or shell abrasion near the hem and cuffs. Disclose each one in the listing and in the photos.

A practical rule: if you would hesitate to tell a buyer the jacket will be warm in cold weather without caveats, it is not Very Good. Grade it Good and say why. A buyer who expects Good and gets Good does not file a dispute. A buyer who expects Very Good and finds clumps does.

## Photographing and listing the finding

The grade only protects you if the buyer can see what you saw. Add these shots to the usual front, back, and tag photos:

- A side-angle shot showing loft and baffle shape
- A close-up of the shoulder and chest baffles
- The zipper, fully zipped, then partly open
- Any flat spot, clump, repair, or leak point, with a finger for scale
- The inside label, which lists fill type and fill power when present

In the description, state what you tested and what happened. For example: all baffles recover within two seconds, no leakage on lint roller test, zipper runs smooth. Specific, checkable statements beat adjectives like pristine or warm. On eBay, match your item specifics to the grade you assigned so the listing and the condition field do not contradict each other. On Mercari and Poshmark, put the finding in the first lines of the description, before the buyer has to ask.

Do not promise warmth ratings you did not measure. Report fill type from the label, report what you observed, and let the buyer judge.

## Grade one puffer and see the report

Pick the puffer in your pile that you are least sure about, the one that sits between Very Good and Good. Run the squeeze test and baffle check above, then grade it in GradeThread. You will get a 1.0 to 10.0 grade, a report across Fabric Condition, Structural Integrity, Cosmetic Appearance, Functional Elements, and Odor & Cleanliness, and a certificate a buyer can verify. Compare it to your own call and see where you landed.
