packdad Washing left my sleeping bag with big clumps and cold spots that shake out but keep coming back. Followed the tag on a front loader with down soap, low spin, then air dried it over a couple days. Still not sure what step threw it off this time.
PinePeak Down clumps like that usually trace back to the drying stage even when the wash went by the book. Air drying lets the fill settle without enough movement to separate the clusters. A low-heat tumble with a couple tennis balls breaks them up without overheating the down.
FogTrek PinePeak has the drying stage pinned down correctly here. Air drying leaves the fill without any agitation, so the clumps reform even after they seem shaken out. A low-heat tumble with tennis balls is the step that actually redistributes everything evenly.
