Why we recommend wearing a technical base layer for a healthy, beneficial habit.: A base layer is an insulating layer that keeps you warm. It also absorbs moisture to leave your skin dry by wicking perspiration away to the outside. It also helps maintain your internal body temperature at 37°C during exercise, in both hot and cold weather. It dries very quickly. It can continue to do this over a longer period by wicking perspiration to keep you comfortable for longer. What our design team has to say: Our team of footballers designed this Keepcomfort base layer top for footballers and sports users looking for a close-fitting base layer that's not too tight, to wear in cold weather. The product is very comfy for moderate intensity play or sports activity that makes you sweat a little. How is this product eco-friendly?: For the black model, the polyester fibre is 100% recycled. This drastically reduces CO2 emissions. The colouring process used is called Dope Dyed, where the thread is coloured in mass. This method considerably reduces CO2 emissions.
