Heck I'd take issue with the fits most…
I had the best lightweight compressible North Face beanie that I left on the subway in NYC when I was there working all winter long. It was windproof and quite warm. Particularly for how thin it was. The subways were warm, however, and I'd have to take it off and unbutton my coat. Had it sitting in my lap and forgot about it when I got up after a 14 hour day at the client site and just zoned… I've never been able to replace it. What made me think of this is that I tried on probably 20 different beanies at the outdoor provision store in manhattan to find one that fit. They only had one of the north face ones in stock – i went back trying to find another one – and had to try on a good 20 more to find the spyder fleece beanie which only worked because it stretched a good bit but was not nearly as windproof…
I pretty much have to try a hat on. Ball caps included even with velcro backs as some still are too small in the body of the hat.
Nike has a range of elasticized dry fit mesh ball caps that also fit well, partly because the mesh stretches but I've had a hard time finding them as well.
It's hard life for those of us with big brains! :-p
