Correctly layering clothes for outside will keep you comfortable and protect you from the elements. Learn about the three key layers, when you should wear them and which materials will work the hardest for you.
How to layer your clothes
Whether layering clothes for winter or summer, each layer of clothing has a function.
Base layer clothing is the layer closest to your skin, which means its main role is in managing moisture and regulating your temperature.
Mid-layer clothing keeps you warm but remains breathable so that it can be used during different weather conditions.
Outer layer clothing shields you from elements like wind, rain and snow and is often less of an insulator than a protector.
Once you have all three, simply mix and match the layers to suit the conditions and personal preference: wear all layers if it’s freezing and wet, or just the base and outer layer if it’s hot and windy.
How to choose base layer clothing
The base layer (you might also know them as thermals) is your next-to-skin layer. Its function is to wick sweat away from your skin so you feel dry and comfortable — rather than cold and clammy — which is especially important when wearing layers in winter.
Base layer clothing also regulates body temperature. In cold conditions, a snug-fitting base layer will trap body heat and keep you warm, while in warmer conditions a loose-fitting base layer will allow air to freely circulate and keep you cool.
The best performing base layer clothing for outdoor adventures is generally made from Merino wool or synthetic, such as:
KMDCore polypro: this provides lightweight warmth for everyday adventures
KMDMotion thermals: this provides superior insulation in high-energy activities
KMDAscent: keeps you warm and dry in alpine conditions.
Merino wool serves as the ultimate base layer as it suits various weather conditions, keeping you warm in winter but remaining breathable.
Layering clothes with a quality mid-layer keeps you warm by trapping body heat in its fibres.
Fabrics like wool and fleece are great for this and have the added bonus of being highly breathable, light and moisture-wicking. This means that it will continue to move moisture away from your base layer and keep you dry as you sweat. This is ideal when moving from the early morning during a hike to mid-morning when the sun starts to heat you up and you start to sweat.
Wool and fleece also have a great warmth-to-weight ratio, providing comfort without the bulk. A lightweight fleece makes an excellent hiking companion: it's light in your pack and will keep you warm on gusty summits.
