Wearing an undershirt is useful for several reasons: in winter it becomes a shield that protects us from the cold air, but at the same time guarantees high breathability. During the warmer months, however, the undershirt allows us to stay dry, in fact, this absorbs excess sweat and allows the skin to breathe better even on the hottest days. However, the construction and manufacturing techniques of the fabrics change according to the season. In spring and summer There are different features to focus on. Assos' latest development in this field is the Skin Layer P1.

The Swiss sportswear brand Assos has taken up the project of the Skin Layer P1 undershirt, improving it. One of the first things that were done was to study a solution to make this product more elastic and more breathable, all while reducing the weight by 15 percent. The yarns used are divided as follows: 68% Polypropylene 29% Polyamide 3% Carbon Fiber

A blend of fabrics designed to create an elastic and extremely enveloping shape. This ensures a better fit to the athlete's body, similar to a second skin.The more open structure with which it is sewn allows for greater air exchange and therefore a lot of breathability, a fundamental technical feature in summer. Assos has also added a permanent anti-odor property, which does not fade even after several washes. 

Technical features

The design with which the Skin Layer P1 undershirt is constructed has a deep cut in the collar. Furthermore, the length of the sleeves is inspired by the characteristics of the Regular Fit model Designed for endurance activities. The cut also prevents bunching that can interfere with the fit.

Assos chose the ultra-stretchy Circular Seamless open-structure mesh, infused with a permanent carbon treatment for odor control. This allows for an increase in the already high breathability and air circulation.
