Base layers are clothes worn closest to your skin to help keep you warm while absorbing sweat. These are especially useful in cold climates or during certain sports, for example running, cycling or skiing.
Base layers have an array of benefits. However, the main benefits of base layers are:
Base layers offer both ventilation and breathability, meaning they can keep you cool in a warm environment but also warm when the cold sets in. Because of this, the right base layers can help regulate your temperature and keep you comfortable whatever the weather.
Base layers are known for wicking. This is when moisture is moved from the skin to the fabric. This is why wicking fabrics are widely popular for sports clothing as they can remove sweat and keep your skin dry.
One of the most popular fabrics for base layers is merino wool. This is sourced from merino sheep so is guaranteed to feel both soft and comfortable. As well as this, merino wool boasts breathability and warmth, so is ideal for cooler climates. Unlike a lot of other materials, it’s also naturally anti-bacterial, meaning it will resist odours.
While merino wool is an excellent natural material for base layers, some man-made materials can also be used. For example, polyester with lycra or elastane make stretchy and comfortable base layers. They tend to be hard wearing and quick drying, but can hold onto unpleasant odours over time.
