This Engineer Jac-Overshirt is proper kit—hard-wearing, high-density, and ready for the daily grind. Whether you're navigating the machinist’s bay or a deep-sea research lab, this is built for those who appreciate a bit of real substance. When the weather’s having a bit of a wobble—that sweet spot between seasons—you need a versatile bit of kit that serves as a proper buffer. It’s all about finding that perfect balance between a casual shirt and a jacket. The Fabric & FeelWe’ve gone for a high-density cotton that’s got some real backbone to it. It’s a medium weight, so it feels solid but won’t weigh you down like a lead weight. It’s got that vintage texture right out of the gate, but it stays crisp and holds its shape, so you’re not looking like a crumpled bag of crisps by midday. The BuildIt’s unlined, keeping it light and easy for layering. Think of it as the perfect middle ground—stuck right between your favourite casual shirt and a proper jacket. Throw it over a T-shirt and you’re sorted. The DetailsSnap & Go: We’ve kitted it out with YKK snap buttons all the way down. No faffing about with buttons when you’re in a rush; just snap it and get moving. Pockets for Days: You’ve got two proper flap pockets on the chest for your essentials, plus two massive side entry pockets for your hands or whatever else you’re lugging about. The Silhouette: It’s cut with a standard shoulder, giving you that sharp, military-inspired look without being too "costume." We’ve kept the length a bit shorter—more like a jacket than a long shirt—so it sits clean on the waist and looks dead sharp. FEATURES 9.7oz./yd.² (330g/m²), 100% Cotton, High-Density.
