Base Layers are worn close to the skin to add extra warmth in the outdoors. Our range of Thermal Base Layers includes a comprehensive range of clothing including long sleeve tops, short sleeve tops, leggings and pants to be worn as your bottom layer when hiking, camping or spending long periods of time outdoors. With a range of brands, styles and materials to choose from, our range includes Base Layers for every requirement. All our Base Layer clothing is made from either Synthetic High-Wicking Fibres, soft and comfortable Merino Wool or a mixture of both. Remember - cotton is ineffective as a base material, as it traps moisture at the skin and prevents it from evaporating. With Free Mainland UK Delivery and No Hassle Returns you're certain to find a Base Layer for every requirement in our Base Layers online store.
