This might seem obvious, yet dressing to stay warm is a science that many of us are flunking. The rule of thumb is three layers.

The first layer, thermal underwear, keeps you both warm and dry—it should be thin, soft and able to “wick” moisture away from your body. Forget cotton and wool, as they trap moisture; instead, invest in a good synthetic fibre like polypropylene.

The second layer needs to fully insulate your body and continue moving any moisture away from you—fleece will do the trick.

The outer layer is your shell. It needs to vent the moisture, and protect you from cold wind and wet snow.

Ensure your layers can be easily removed to avoid overheating; if you’re doing an intensive workout, a wicking layer and shell may be all you require. And don’t try to be too cool for school by forgoing a hat, scarf or neck warmer and waterproof gloves; waterproof footwear and warm insulating socks are also a must. You don’t want to have to cut short your activity because you’re cold and wet.
