Men's Thermal Underwear & Base Layers

For added warmth on top of your base layer, consider a men’s softshell jacket. Our range features softshell jackets with a variety of different functions, from waterproof to windproof in a variety of styles and colours. Softshells are perfect for layering; they're lightweight and easily compacted, allowing you to store them without sacrificing much-needed space. To ensure all your extremities are warm and protected from the elements, visit our caps, hats and gloves.
