I bought one Chaos hat and loved it. Came back for another and Hate it!  This one is very Different It is a little too tight, and the yarn doesn't want to give as much as the first one did.  I can't stretch it to fit. I have poor circulation - therefore this hat will not work for me! ! !
  I think the yarn may be a different brand or something.  Totally different from the first hat I bought as a test.
