What’s this? A button-down that can pass the spring to summer wardrobe transition? You betcha. If you like to cover up in the heat but don’t want to be drenched in sweat before you can even pull on and button up your shirt all the way, Portuguese Flannel‘s Long Sleeve Linen Shirt is the textile air conditioner for you.

Made from 100% linen, this navy-dyed summer breeze is the diplomat of shirts, effortlessly pairing with anything – or any season – you can think of,  from the most middle school of shorts, to your favorite pair of raw denim jeans. This is thanks, in part, to the spread collar and mother of pearl buttons which give off an air of elegance without a thread of stuffiness. Rounded out with a rounded hem and trim fit, this made in Portugal shirt is an instant summer standard.
