Rogue Tin Cloth 405 Legend Hat

Growing up, boys have an adventure hat in their minds. Then you grow up and realise that hat doesn't really exist. All hats are too neat and tidy, too small/big/uncomfortable/just not right.
BUT, not this one. The 405 is brilliant. Comes out the box looking like it's already got stories to tell, and the second you try it on you want to go find more stories. Really comfortable (I triple-checked sizes as per the caution), simple design that just works. Mine's on its way to the KNP on Saturday. Thank you Trappers. Ordered it very late in the day, fully expecting to not have it in time. But it arrived 2 days early! Great service. Great hat.
