A sport base layer top, often called a technical or thermal base layer top, helps to: . retain body heat when the product is slim fitting. . absorb perspiration and transfer it to the outside. Your skin stays dry to prevent chilling . provide an additional barrier against bad weather . keep your football shirt dry, even when you're running hard. Playing with a technical base layer keeps you on the pitch for longer.

The complete outfit: base layer top and tights. Its design is inspired by the weave. The new fabric better manages moisture and retains body heat. There is a large amount of polyamide to reduce odours. The warmer body parts have been mapped and given a more open knit. Features such as the thumb hole and the 3D knit reduce the impact if you fall on your elbows, knees or hips The product withstands pulling.

We're always listening to our users, and as a result we've crafted a product that meets the needs of more experienced players. In the heart of the action, the pace of play picks up and the intensity varies more. Clothing must be ultra breathable to regulate your body temperature during the most intense phases of play. Your base layer should also be close-fitting in order to quickly absorb perspiration while keeping your body warm.

These tights are made from a weave that blends a polyester thread (67%) to help wick away perspiration with a polyamide thread (30%) for greater softness and no unpleasant odours. These two threads, combined with elastane, ensure excellent comfort and a second skin effect.

The combination of the fabric and the seamless technology offers excellent thermal regulation so you can play hard without getting chilled.

The range of available colours makes it easy to match with your kit so that you can comply with competition rules.

The product's environmental impacts are calculated throughout its life cycle and with different indicators. An overall ABCDE rating is performed to help you easily identify the products with the best environmental performance by comparing the same type of products with each other (t-shirts, trousers, backpacks,...).
