Men's Brushed Cotton Pyjamas

Cold nights call for pyjamas that actually keep the heat in, and brushed cotton is the fabric built for the job. Mariner Underwear's men's brushed cotton pyjamas sit at the warmer end of our nightwear range, built from a soft, slightly raised cotton weave that traps heat without feeling heavy. The range covers two styles: a traditional open-front pyjama set with a buttoned jacket and straight trousers, and a bi-material set that pairs a jersey top with checked flannel bottoms. Mariner Underwear has worked with French textile know-how since 1967.

Pure Brushed Cotton Flannel and Warmth

Brushed cotton, often called flannel or flannelette in the UK, starts as a woven pure cotton cloth that gets brushed on one or both sides. The brushing raises tiny fibres from the weave, which traps air and holds body heat close to the skin. That is why a flannel pyjama feels warmer than a plain woven fabric at the same weight, and cotton stays breathable even at that thicker weight. Most of the range is combed before weaving, which removes short fibres so the finished flannel feels soft rather than scratchy, and the weave keeps its shape rather than thinning out after regular wear.

Open-Front Brushed Cotton Pyjamas in Grey, Navy and Red Check

The classic style in this collection is an open-front pyjama set: a buttoned jacket in tartan check paired with plain straight trousers that have a fly opening. It is a traditional cut, designed for a relaxed fit rather than a close one. The checked jacket comes in grey with a mottled effect, navy with a burgundy trim, and red-and-navy check, each paired with a matching plain trouser. Most of these sets are pure combed cotton flannel throughout. On one grey style, the jacket blends 70% cotton with 30% polyester while the trousers stay 100% combed cotton.

Comfy Bi-Material Sets: Button Collar and Checked Flannel Trousers

A second style in the range combines two fabrics in one set. The top is a buttoned-collar jersey in brushed combed cotton with a peach-skin touch, and the trousers switch to checked flannel. Ribbed trims at the cuffs and hems add extra warmth. The trousers close with a drawstring waist and a faux fly finished with decorative buttons. This style comes in petrol blue, mottled anthracite, charcoal grey and burgundy, each with its own check pattern on the trousers.

Which Brushed Cotton Pyjamas to Choose

The open-front set suits anyone who wants a fully buttoned jacket, easy to put on and adjust without pulling anything over the head. The bi-material set trades that for a pullover-style top, which some men find quicker to get into on a cold morning. Both styles use the same weight of checked flannel on the trousers, so the choice comes down to how you like to put the top on rather than how warm it keeps you.

Nightshirts and Checked Flannel Trousers in the Same Range

The collection also includes a buttoned-collar nightshirt in the same checked flannel, cut long and worn on its own or over trousers. See the full men's nightshirt collection for more styles cut the same way. For a lighter option, checked flannel trousers with an elasticated waist and drawstring are sold on their own, finished with a side pocket on each hip and a faux fly, and easy to pair with a t-shirt around the house during the cooler months. One version comes from a Mariner Underwear collaboration with Chevignon, in the same tartan check flannel.

Comfy Fit and Sizing

Sizes run from S to XXL across most styles, with some flannel trousers starting at size M. Take your normal size, since the cut is designed for a comfy, relaxed fit rather than close to the body. The roomier fit also leaves room for a t-shirt or thermal layer underneath on the coldest nights, without the waistband feeling tight.

Nightwear or Sleepwear for Cosy Evenings

Call it nightwear or sleepwear, either way this cosy checked flannel range suits sleeping through a cold night as much as it suits sitting around at home before bed. The same tartan check runs through the open-front jacket, the bi-material trousers and the standalone flannel trousers, so any piece from the range pairs easily with the others.

Completing Your Nightwear

For lighter nights, the men's cotton pyjamas collection swaps flannel for a smoother woven cotton. The full men's pyjamas range brings together every cut and fabric Mariner Underwear makes, so you can match the pyjama set to the season.

Frequently Asked Questions

What is brushed cotton?

Brushed cotton, also called flannel or flannelette in the UK, is a woven cotton fabric that has been brushed on one or both sides to raise a soft layer of fibres. That texture traps air and keeps you warmer than a plain cotton weave, which is why it is a common choice for winter pyjamas.

Are brushed cotton pyjamas warm enough for winter?

Yes. The brushed finish holds body heat close to the skin, and Mariner Underwear's flannel sets use combed cotton for extra softness. The open-front sets and the bi-material sets with ribbed cuffs both add warmth at the sleeve and leg openings.

What is the difference between flannel pajamas and brushed cotton pajamas?

There is no real difference; both have a fuzzy surface. "Brushed cotton" is simply the more common name for the same fabric; in the UK, both terms are used to describe the same pajama sets.

How do you wash brushed cotton pyjamas?

Wash on a gentle machine cycle and let the flannel air dry when you can. Brushed cotton is durable and holds up to repeated washing without losing its softness, but a lower heat setting protects the brushed finish for longer.

What size pyjamas should I buy?

Take your normal clothing size. Mariner Underwear cuts its pyjama sets for a relaxed, comfortable fit rather than a close one, and sizes run from S to XXL.

What is an open-front pyjama set?

An open-front set pairs a fully buttoned jacket with separate straight trousers, unlike a pullover-style top. It is a traditional pyjama cut, and Mariner Underwear makes it in tartan check flannel.

Can men wear a nightshirt instead of a pyjama set?

Yes, a nightshirt is a one-piece alternative to a two-piece set, cut long and worn on its own. Mariner Underwear makes a buttoned-collar nightshirt in the same checked flannel as its pyjama sets, for anyone who prefers a single garment.
