How to layer clothes for UK weather: warm, dry and not too hot indoors

Why layering works

Each layer traps a little warm air, and still air is a good insulator. Thin layers also let you adjust. If you warm up walking to the station, unzip or take a layer off. If the wind picks up, add one back. One very thick coat over a T-shirt gives you two choices: too hot or too cold.

Layer 1: the base layer

This is the layer next to your skin. Its job is to feel comfortable and to move moisture away from you when you get warm.

• Merino wool is soft, warm and slow to hold smells, which makes it a good choice for long days.
• Synthetic base layers, often polyester, dry quickly and suit active days.
• Cotton T-shirts are fine for a cold, dry day in town, but they hold on to sweat and dry slowly, so they are less comfortable if you are walking far or getting warm.

Thermal tops and leggings are worth having for the coldest weeks.

Layer 2: the mid layer

This is your main warmth.

• Knitwear: a wool or cashmere jumper is warm for its weight and looks smart. Our guide to washing and storing knitwear explains how to keep it looking good.
• Fleece: light, warm, quick-drying and easy to wash.
• Gilets: a padded or down gilet keeps your core warm while leaving your arms free.
• Cardigans and overshirts: easy to take off indoors.

On colder days you can wear two mid layers, such as a fine knit under a gilet.

Layer 3: the outer layer

This protects you from wind and rain, which is often what makes a British day feel cold.

• Waterproof jackets keep rain out. Taped seams and a good hood make a big difference in heavy rain.
• Water-resistant jackets shrug off a shower, but not a downpour.
• Windproof layers stop the wind cutting through your warm layers.
• Wool coats are warm and smart for town, but less good in heavy rain unless treated.
• Padded and down coats combine warmth and outer layer in one, for the coldest days.

Look for "breathable" on waterproofs if you walk a lot, so you do not get damp from the inside. Check the care label too, since many waterproofs need gentle washing to keep working.

Make sure your coat has room for your layers underneath. Our guide to how a winter coat should fit explains how much room to leave.

Do not forget the extras

• A hat, for cold or windy days.
• A scarf, which is quick to add or remove.
• Gloves, especially on cold mornings.
• Warm socks, ideally wool blends, and waterproof footwear for wet days. Our guide to buying second-hand winter boots covers what to check.

Layering through the seasons

• Autumn: a T-shirt or shirt, a light knit and a water-resistant jacket.
• Winter: a thermal or merino base, a warm jumper or fleece, and a waterproof or padded coat, with hat, scarf and gloves.
• Spring: a long-sleeved top, a cardigan or overshirt, and a light waterproof, because showers come and go.
• Summer: a light layer for evenings, and a packable waterproof just in case.

Indoors and out

The British problem is not just the cold outside. It is moving between cold streets and warm buses, trains and offices. Front-opening layers, such as zipped fleeces, cardigans and gilets, are easier to adjust than pullovers. A coat with a two-way zip or poppers lets you open it a little without taking it off.

Layering second-hand

Layering pieces are some of the best things to buy second-hand. Fleeces, knitwear, gilets and waterproofs are built to last, and good ones are well worth looking for.

When you buy, check:

• Knitwear: pilling, holes and the composition label.
• Waterproofs: the seams, any peeling inside, and the zips and hood.
• Down and padded pieces: even fill, with no flat patches. Our guide to washing a down jacket explains how to restore one.
• Fit: ask for the chest and length in cm, laid flat, so you know your layers will fit underneath. On Rewear, tap Message the seller if they are not in the listing.

If you are clearing out layers you no longer wear, autumn and winter are good times to list them, when buyers are looking.

The short version

Base layer, mid layer, outer layer. Several thin layers beat one thick one, wool and synthetics stay warm when damp, and front-opening pieces make it easy to adjust between cold streets and warm trains.
