I washed a down jacket and expected it to survive?

[Justsewsew]

I bought an as new Land's End down jacket from Vinted and washed it today on a 30 degree wash. The filling has clumped up in the channels and I now notice it should have been a cold wash only. I've tumbled dried it on low but it's mot getting any better. Is there anything I can do to redeem it? 😭

Woah. I will stick to my synthetic anyway as I will get sick from allergies.

My down-filled gilet was fine washed at 30 (my otherwise hated Beko machine has a down programme). The care instructions were clear NOT to tumble dry but keep shaking it in all directions to fluff up the down. It used to take about a week to fully dry, but lots of shaking did the trick to redistribute the filling.

Same -no tumble drier for my down jacket but found a hack online. Once it’s almost dry on the airer, move to flat surface and batter the clumps out with a rolling pin. It works and it’s quite therapeutic (picturing my POS ex H).

So were we - it was second-hand but unused (some other poor sap bought it) and gave it to DH. I took one look at it and said to him, no chance will any of them use that... I put it on the spare bed thinking it was a complete waste of time and the rest is history.
