This fabric! It's a perfect summery chambray blue with a rich large-scale three-dimensional herringbone. It's like nothing we've ever seen before. Stetson Europe really delivered this season. The shape is an old-fashion flat cap with full sides and a curved bill. There's a bit of space between the brim and the body of the hat, which is sewn down (no snap). The top and back of the body are one continuous piece, with side panels for shaping. We love Stetson Europe's linen caps for their breathability even on the hottest days of summer.
