Simply the best all weather hat one can buy!  It allows the breeze to move through, keeps the rain and snow off, comes with a chin strap and it is actually made in the USA!  The sensei at the dojo I attend loved it (we may have to get him one...)and he said something about everyone having to have one by next summer for the yard work!

I'll proably buy a second one for when the first one wears out, if ever.

It's a great hat!
