A quart or maybe 40oz size was the one that Judie bought and my jacket is butter soft. I really don't get into the laundry much except when something is broken so I really don't know the size but that is the approximation from the jug I saw.

Also another tidbit for the green jackets, washing with Borax helps retain the flame retardance and makes them last longer too. Borax also works for the hats and skull caps.
