Cotton jersey construction that breathes throughout the day and sits softly against the skin - substantial enough to wear as a layer without feeling stiff or heavy. Full snap-button placket runs the length of the front, giving it a cleaner finish than a standard shirt and making it easy to throw on and off. Single chest patch pocket adds a workwear edge without overcomplicating the silhouette. Regular fit through the shoulders and body - it hangs with a relaxed ease that doesn't pull or bunch when worn open over a tee. The structured collar means it reads more like a jacket than a sweatshirt, sitting flat and holding its shape across the shoulders. The cotton jersey has a lived-in softness from the first wear - not the kind that needs breaking in over several washes. It moves with you rather than against you, which makes the all-day wearing claim genuinely believable. The overshirt sits at that useful midpoint between a shirt and a light jacket: too relaxed to be formal, but put-together enough that you're not just reaching for it on a lazy Sunday. Worn open over a plain white crew-neck tee and straight-leg jeans - as the model shows here - it works for a Saturday afternoon out or a casual pub evening without any effort. Fasten the snaps and it becomes something closer to a coach jacket. It's the kind of piece that gets picked up first because it goes with almost everything already in the wardrobe, and never needs overthinking.
