Men's Long-Sleeve Cotton Overshirt Relaxed Fit Double Pocket Flannel Shirt is your go-to choice for effortless layering or wearing solo all year round. Cut in a relaxed silhouette from 100% premium cotton, it features double chest pockets and tonal buttons, making it ideal for men who want understated utility with a lived-in finish.

Why You'll Love It

  • Double chest pockets: Practical patch pockets with button closures add subtle workwear character without bulk.
  • Relaxed fit: The easy, unstructured silhouette works equally well open over a tee or buttoned up as a standalone shirt.
  • Washed cotton finish: A soft, broken-in look gives the shirt a timeless, lived-in appeal straight from the hanger.

Perfect For

Layer it open over a white tee for a casual weekend look, or button it up for a smart-casual pub lunch. Pairs well with chinos for a city stroll or with jeans and trainers for a relaxed day out. A solid choice for countryside walks or low-key travel days too.

Care Instructions

  • Machine wash at 30°C on a gentle cycle.
  • Do not bleach.
  • Tumble dry on a low heat setting or lay flat to dry.
  • Cool iron if needed, avoiding direct contact with buttons.
