SO we got these in, gave em a wash before our son was to wear them (we always do that so the factory dyes and other etc will get removed first + he has excema so our dye free detergant helps remove junk that might irritate him).

We washed them, cold and cold, and than hung em to dry. I put in dryer on 'air only' cycle which only cycles room temp air thru, and we stuck a fabric softener sheet in there.

We were amazed they almost shrunk a pantsize.
HOWEVER with that said i don't forsee it shrinking any more and am please to have them
