Called Second Skin because the fabric is worn next to the skin where it is most effective. Produced from a luxurious micro-fibre which is soft, supple lightweight and exceptionally comfortable. It will feel like a second skin. Second Skin will keep you warm and dry in all conditions because it breathes without any loss of thermal properties, transferring moisture and perspiration to the outside.
