I'm glad to know that I'm not the only one to deal with this scourge!
The problem with my finding another coat to finish out the winter is that I wear an uncommon size, XXSP. I am very short and have very narrow shoulders, and coats that aren't petite sizing just don't work for me. So the coats are very picked over at this point, and the ones that I see are left do not look very warm, or else they do not cover my backside (coverage is a necessity in my climate).
But I wonder if I try something like putting sealant on the seams (I could try some Fray Check, which I used to use when I did cross stitch) if Macy's will refuse to take it back. Sometimes stores don't want to take back stuff that's been messed with.
This is my third puffer, and I have never had this issue before. My other two would occasionally sprout feathers, but it wasn't anything that made me wonder what was going on. My previous puffer did start to release a lot of feathers, but at that point I discovered it had a small hole in it, which I fixed. Even the amount of feathers released by that puffer is nowhere near what I experience with this one.
Bonus question: When I wash this puffer and dry it, it has an awful odor, like sour sweat. When I take it out of the washer it smells fine--it's the drying that causes the odor. Is this normal?
