Men’s Turtleneck Sweaters: How to Wear a Roll Neck

A men’s turtleneck sweater is the most useful winter knit after a crew neck: worn under a blazer it replaces a shirt and tie, under a coat it replaces a scarf, and with denim it looks quietly sharp. Coveti’s picks start with the Brunello Cucinelli cashmere turtleneck from the men’s Winter Edit, alongside more roll necks in our men’s knitwear edit.

Turtleneck, roll neck, polo neck, mock neck: what is the difference?

Mostly vocabulary. In the US the tall folded collar is a turtleneck; in Britain it is often a roll neck, and older British tailors call it a polo neck. All three mean the same thing: a tube of knit at the neck, folded over once. A mock neck is different. It stands up without folding and sits lower, so it reads as a lighter, more casual version. The Jersey mock neck T-shirt in Navy Blue is the lightest way into the shape, cotton jersey that sits neatly under a jacket in the shoulder seasons.

The house of Brunello Cucinelli began in 1978 with knitwear in coloured cashmere, and that is still the best fibre for a roll neck worn against the skin. Our guide to Brunello Cucinelli menswear explains the wider line, and our men’s cashmere sweater buying guide covers ply, gauge and care.

The turtlenecks we would buy

The Cashmere turtleneck sweater in Panama is 100% cashmere in a warm sand neutral, which goes with grey flannel, navy and every shade of brown. If you buy one roll neck, buy this kind.

For more texture, Herno’s Cable-Knit Wool Roll-Neck Jumper in Milk White is the chalet version, chunky enough to wear as your top layer indoors. Herno’s Wool and Cashmere Roll-Neck Jumper with Norwegian Pattern in Bordeaux brings colour and pattern for weekends. Moncler’s Wool Blend Polo Neck Jumper in Black is the city choice, smooth and dark under a coat. And Mackage’s Legend Knit Cotton-Blend Turtleneck Sweater in Coffee is a good option if wool against the neck bothers you.

How to wear a turtleneck with tailoring

This is where the roll neck earns its keep. A fine cashmere turtleneck under a blazer is as smart as a shirt without a tie, and in winter it is often smarter, because it looks chosen. The rules are short:

• Keep the knit fine. A chunky roll neck pushes the lapels open and crowds the collar. Fine gauge sits flat.
• Match the depth, not the colour. A sand knit with a mid-tone jacket, navy with grey, black with charcoal. Tonal looks expensive.
• Let the jacket do the structure. The Chevron Tailor blazer in Panama, with its structured shoulder and wide lapels, frames a roll neck well. A full suit works too, as our Brunello Cucinelli suits and blazers guide shows.
• Finish with suede. Derbys and boots in suede sit better with a roll neck than polished black calf.

How to wear a turtleneck with a coat

A roll neck under a tailored coat does the job of a scarf, keeps the line clean at the collar and looks deliberately spare. The Chevron coat in Dark Grey over the Panama turtleneck, grey trousers and brown boots is a complete winter outfit with nothing extra needed. For more coat shapes, our best luxury winter coats for men guide is the place to look. Over a parka, a chunkier roll neck such as the Herno cable-knit works better, since the parka hood sits behind it.

How to wear a turtleneck casually

Off duty, a roll neck makes a leather jacket look grown up. The Suede biker jacket in Light Brown over a sand cashmere turtleneck with No-fade denim trousers is about the best weekend uniform we know. See our men’s suede jackets guide for more. A patterned Norwegian roll neck with cords and boots is the country version, and we have built more combinations in our old money winter outfits for men.

How should a turtleneck fit?

The neck should fold once and sit comfortably, not grip. If you can slide two fingers inside the fold, it is right. The body should skim rather than cling: a roll neck that is too tight emphasises every line, one that is too loose sags at the collar. For wearing under tailoring, keep the shoulder seam at the edge of your shoulder and the hem at the top of the hip, so it tucks neatly under a jacket. Coveti shows Brunello Cucinelli numbered knitwear as UK/US chest, Italian size minus 10; the mock neck tees are in letters, XXS to 4XL.

Which fibre is best for a turtleneck?

Cashmere is the softest against the neck, which is why it is the classic choice for a roll neck worn under a jacket. Wool and wool blends are sturdier and hold a chunky cable well, which makes them better outer layers. Cotton and cotton blends work for milder weather and for anyone who finds wool itchy. Silk blends add a little smoothness and drape. Whatever the fibre, wash and fold knits carefully; our how to wash cashmere guide applies to most fine wools too.

Frequently Asked Questions

How should a man wear a turtleneck sweater?

Wear a fine cashmere turtleneck under a blazer in place of a shirt and tie, under a tailored coat in place of a scarf, and with a suede jacket and denim at the weekend. Keep the colours tonal and the shoes in suede.

Can you wear a turtleneck with a suit?

Yes. A fine gauge turtleneck under a suit is a smart winter alternative to a shirt and tie. Choose a knit thin enough to sit flat under the lapels and a colour close in depth to the cloth.

What is the difference between a turtleneck and a mock neck?

A turtleneck has a tall collar that folds over once. A mock neck stands up without folding and sits lower on the neck, so it looks lighter and more casual.

Is cashmere good for a turtleneck?

Cashmere is the softest fibre against the neck, which makes it the classic choice for a turtleneck worn under tailoring. The Brunello Cucinelli Cashmere turtleneck sweater is 100% cashmere.

How tight should a turtleneck be?

The collar should fold once and sit comfortably with room for two fingers inside the fold. The body should skim, not cling, with the hem at the top of the hip.
