Portuguese Flannel does laid-back summer shirts better than almost anyone, and this monochrome check option is proof. Made near Guimarães, Portugal, from pure organic cotton, it has a lightweight, breathable feel that keeps you cool when the temperature climbs. The camp collar and relaxed silhouette give it an easygoing, retro-inspired look. The blurred black-and-grey check pattern feels modern and pairs easily with dark denim or simple linen trousers. Finished with classic button fastenings and a single chest pocket, it is an easy throw-on option for weekend pub gardens or warm holiday evenings.
