I didn\'t take my boonie hat to the mountains but I wished I would have. Mine old one is cotton so I thought I would look for one in a different material for next year. I found this one from Drake Waterfowl, <!-- m --><a class=\"postlink\" href=\"http://www.drakewaterfowl.com\" onclick=\"window.open(this.href);return false;\">http://www.drakewaterfowl.com</a><!-- m -->. It\'s $20 and is supposed to be waterproof. I\'ll try it out this fall chasing WTs. Thought it was a decent hat and just wanted to share in case anybody else was looking for a waterproof boonie.
