Never had any problems with shrinkage, but only ever use a warm wash or rinse for the coats.
I have used them for years with no problems at all.
Have you contacted "Equafleece" and spoken to them about your problem, they are very helpfull !!
As a coincidence we have just got home today from a hard days work with 3 dogs, they have all just had their warm showers (no shampoo's though)
and they are all wearing their "Equafleece" coats to finish the drying process.
Good luck.
