Down fill distribution between baffles
Whether fill sits evenly between baffles when the jacket is backlit, and whether any chamber is empty.
The reading sequence
4 steps, starting at structural defects and running to read the loft in a side-on view. Evidence on this point is read at E1, and 2 of the 4 steps carries a condition that ends the assessment outright.
Backlight the jacket against a window or a lamp
Get one frame where light passes through the whole body panel, so fill shows as a pattern of shading rather than as an opinion.
Evidence: E1 — one uncut video, 20 seconds, jacket held flat against a bright window or a lamp with the arms hanging free and the camera steady
- Light passes evenly across the body panel, with every baffle shading the same grey.
- Baffle channels read as even stripes from the shoulder to the hem.
- Two or three baffles read lighter than their neighbours at the hem or in one sleeve.
- A bright patch sits where the tape crosses at one point only.
- A whole panel reads white against the rest of the jacket.
- Two or more adjacent baffles look empty with the channel walls touching.
Pinch each channel in three rows
Confirm by hand what the backlight suggests, working along the shoulder row, the middle row and the hem row on both faces.
Evidence: E1 — a video of the seller pinching the cloth between thumb and finger along three rows on the front and three on the back, holding each pinch for two seconds
- Every pinch lifts 10 to 20 mm of fill between the fingers.
- Loft springs back the moment the fingers open, front and back alike.
- One pinch holds visibly less at the hem row while the rest are full.
- A channel beside a side seam feels thin on both faces.
- Two or more adjacent channels collapse flat between the fingers.
- Fill moves away under the hand inside a wide chamber, leaving the area pinched flat.
Shake the jacket and re-read the distribution
See whether the fill stays where it was placed, which is what separates baffled construction from loose fill in wide channels.
Evidence: E1 — a video of the seller shaking the jacket twice by the shoulders and laying it flat, with the backlight behind it for a further 30 seconds
- Fill settles within a minute and the backlight pattern returns to what it was.
- No chamber empties at the top while another thickens at the bottom.
- Fill gathers at the hem after shaking and needs a hand to spread it back.
- One sleeve holds a thin band near the shoulder after the shake.
- Fill drops into the bottom third of the jacket and stays there.
- The upper half goes flat while the hem swells after two shakes.
Read the loft in a side-on view
Decide whether the jacket holds its thickness once it is folded and left alone, which is what the fill does on a body.
Evidence: E1 — one side-on photo of the jacket folded once across the chest and left for a minute, with a tape measure standing against the fold
- The folded jacket holds 6 cm or more of loft after a minute with the tape in frame.
- The two sleeves show the same thickness as the body panel.
- The fold holds 4 to 5 cm of loft while the sleeves stay thicker.
- Loft drops 1 cm over the minute and then holds.
- The fold holds under 3 cm of loft against the tape.
- The jacket flattens to the thickness of its own shell within a minute.
Why the thresholds sit where they do
Fill is the one part of a jacket that cannot be inspected after the fact and cannot be corrected at home, which is why it is read before any surface question. Backlighting is used first because it converts an invisible property into a pattern that two people can describe the same way, and hand pressure is used second because a backlight cannot distinguish a thin chamber from an empty one. The shake test then separates baffled construction from loose fill, which is the difference that decides whether the jacket stays warm in month two. The 6 cm loft figure is set from folding the same jacket three times on one afternoon; it is a floor, not a specification.
Common misreads
3 pairs recorded for this point. Each runs in both directions: 2 findings that looks worse than it is, and 1 that looks better.
- looks like Return actually Pass
A backlit jacket with a bright band across the shoulders. Shoulder panels carry less fill by design so the arms can move, and the pattern there is not a cold spot.
- looks like Pass actually Query
A full, lofty jacket photographed on a hanger with no backlight. Loft in a photograph depends on how the jacket was arranged a second earlier, not on how much fill is inside.
- looks like Return actually Query
Fill that gathers at the hem after a hard shake. Every down jacket moves some fill when shaken, and the question is whether it spreads back by hand.
