Layering that beats the cold
In sub-zero cold, layering and wind protection are key.
In a cold snap, wind matters more than thickness. At the same temperature, every 1 m/s of wind drops the feels-like about 1°C, so one windproof shell often beats a single thick garment.
The baseline is a three-layer build: thermal → knit → puffer. Several thin layers trap air and beat one thick one. Sealing just the neck, hands and feet lifts how warm you feel, so a scarf, gloves and boots are essential.
Styling tips
- 3-layer: thermal → knit → padded
- Warm neck/hands/feet (scarf, gloves)
- Windproof outerwear
- Fleece-lined bottoms

Frequently asked
How many layers in a cold snap?
Three: a thermal base, a knit, and a windproof puffer. On the coldest days, add another base layer or a vest.
Puffer or thick coat?
For strong wind or long stretches outside, a windproof puffer is safer. In and out of buildings, a wool coat over a thick knit and thermal base holds up.
Are jeans okay in extreme cold?
Regular jeans let wind straight through. Choose fleece-lined ones or wear thin thermal leggings underneath.
