For unknown reasons, it is not really easy to get actual XXL caps, ie not those which are advertised as (X) XL, but then turn out again as a unit size.
This hat definitely passed the test ears perfectly and I am also satisfied, as regards the heat. The described in some reviews disturbing "Lambswool scratching" at least I have not noticed. So Conclusion:
* XXL is really XXL
* Warm
* Not scratchy
* fits perfectly
