How to spot the original Flannel Check Overshirt

Brushed cotton flannel with a soft, slightly fuzzy surface, and a blurred grey, blue and cream check that runs right across the collar, pocket and cuffs.

A single chest pocket on the left with a pointed base and its own button, cut so the check lines up with the front rather than sitting at an odd angle.

Cuffs with two buttons, so you can wear them snug at the wrist or looser, and a pointed collar that keeps its shape when worn open.

The overshirt

Pure cotton flannel

Brushed cotton flannel is soft and warm without feeling heavy.

The grey check pattern is woven through, so it never fades into a flat print.

A neat collar and chest pocket keep it looking like a proper shirt.

Flannel is cotton that has been gently brushed on the surface to raise soft fibres, which is what gives it that warm, fuzzy feel. Because it is pure cotton, it breathes naturally and stays comfortable whether you are walking the dog in the frost or sitting in a warm café afterwards.

The fit

Relaxed, M to XXL

A relaxed fit with a 118 cm chest on the M up to 130 cm on the XXL.

The length is 70 to 76 cm, so it sits over the belt when worn loose.

Sleeves run from 57 to 60 cm, with buttoned cuffs you can roll back.

The fit is relaxed without being oversized, with enough room through the chest for a thin knit underneath. The length covers the waistband, so it looks neat untucked, and the cuffs can be rolled back to the forearm on milder days.

How to wear it

An easy grey check

With light jeans and white trainers, it is a relaxed weekend outfit.

Over a black tee with black jeans, it looks sharper and more modern.

Choose your size above. Free UK delivery.

Grey check is one of the easiest patterns to wear: it works with blue denim, black jeans, stone chinos and brown cords. For a cosy autumn look, add a cream crew-neck jumper over the top and a pair of suede boots; in spring, wear it open over a plain white tee.

From Maria & Denis

A cotton flannel check overshirt is the soft, warm shirt every man needs for autumn walks and lazy weekends.

It is made from pure cotton flannel, brushed for a soft, cosy handle that feels warm the moment you put it on.

The grey check is easy to wear and goes with denim, chinos and cords alike.

A relaxed cut and a patch pocket give it a casual, lived-in look.

Wear it open over a white T-shirt, or buttoned up with a jumper over the top.

Few things feel as good on a cold morning as a soft flannel shirt. Brushed cotton flannel traps a little warm air close to the body, so it keeps you comfortable outdoors and never feels stuffy indoors. This overshirt takes that classic comfort and gives it a relaxed, modern shape that you can wear on its own or open as a light jacket.

Grey check, in sizes M to XXL.

Fabric & care

100% cotton flannel.

Machine wash at 30°C with similar colours, hang to dry.

Cotton is breathable and easy to care for: wash it at 30°C inside out with similar colours.

Hang it to dry rather than tumble drying, which keeps the colour fresh and stops shrinking.

A quick cool iron or a steamer smooths it out in seconds.
