Founded in 1676, British heritage label <a href="http://www.mrporter.com/mens/Designers/Lock_and_Co_Hatters">Lock & Co Hatters</a> is still an industry leader today. Crafted in England from robust virgin wool, this classic flat cap has a clever fleece-lined flap that can be unfurled for added protection against the elements. It's finished with a smooth satin lining and a padded internal grosgrain browband for the most comfortable fit.
