Men's knitwear: a simple guide to sweaters that last

A good sweater is one of the most used things in a cold-weather wardrobe. It goes over a shirt for work, over a tee for the weekend, and under a coat for most of the winter. This guide explains what to look for so you can choose a few that work hard, rather than many that sit in a drawer.

Gauge: fine, medium, chunky

Gauge describes how fine the knit is. You do not need the numbers; you can see and feel it.

Fine gauge knits are thin and smooth. They sit well under a blazer or a coat and look smart with a collared shirt. They are less warm on their own.

Medium gauge is the everyday middle. Warm enough to wear without a jacket indoors, still slim enough to layer.

Chunky knits are thick and textured. They are warm and relaxed, and they usually replace a light jacket on dry autumn days. They are hard to wear under a fitted coat.

If you are building a small set, one fine and one medium knit in neutral colours will cover more situations than two chunky ones.

Necklines

Crew neck is round and close to the neck. It is the most versatile: over a tee, over a shirt with the collar inside, or alone.

V-neck shows a shirt collar and a tie if you wear one. It looks a little more formal and suits a layered work outfit.

Roll neck (turtleneck) covers the neck and replaces a scarf on mild days. It works well under a blazer or overcoat. Choose a fine gauge if you plan to wear it under a jacket.

Quarter-zip and half-zip knits open at the neck. They are casual and practical when you move between cold streets and warm rooms.

Fibres, honestly

Labels tell you the fibre content. Here is what the common ones usually mean in practice.

• Wool is warm and keeps some warmth even when slightly damp. Some types feel scratchy; merino is finer and softer for many people.
• Cashmere is soft and light. It needs gentle care and tends to pill at first.
• Cotton is easy to wash and good for mild days, but it is less warm and can stretch.
• Blends with synthetic fibres are often cheaper and easier to wash. They can pill more and may feel warmer and less breathable.

There is no single best fibre. Pick based on how cold your days are, how you do laundry, and how the knit feels on your skin.

Fit

A sweater should follow your shape without pulling. Check these points:

• Shoulder seams sit at or just past the edge of the shoulder.
• Sleeves reach the wrist bone when your arms hang down; ribbed cuffs can be pushed up a little.
• The hem ends around the top of the hip and does not ride up when you lift your arms.
• There is room for a shirt underneath if you plan to layer.

A sweater that is too tight shows the shirt underneath in lines. One that is too big bunches under a coat.

Layering that looks deliberate

Shirt under crew neck. Keep the collar flat inside, or lay it over the neckline. A button-down collar stays neat.

Tee under knit. Make sure the tee hem does not show below the sweater unless you want that look.

Knit under coat. A fine or medium knit under a wool overcoat is a classic winter combination. See our outerwear guide for coat lengths.

Knit over shoulders. Optional. It works in mild weather and adds a second colour.

Colour

Charcoal, navy, grey, oatmeal, and dark green go with most trousers and jeans. A brighter colour is easiest in a crew neck worn with plain trousers. If you want texture rather than colour, a cable or rib knit adds interest without making matching difficult.

Care that keeps the shape

Follow the care label first. In general:

• Wash knitwear less often; airing it overnight is enough after a short wear.
• Use a gentle or wool cycle with cool water, or hand wash.
• Do not wring. Press the water out in a towel.
• Dry flat, never on a hanger, so the shoulders do not stretch.
• Store folded, not hung.
• Remove pills with a fabric comb or a shaver made for knits.

Wool is attractive to moths. Clean knits before storing them for summer and keep them in a closed bag or box.

A short checklist

Does it fit at the shoulders and wrists? Does it work with at least three things you already own? Can you care for it the way the label asks? If yes, it is likely to be worn often.
