APEX Blue running tank top
The APEX Blue T-shirt is part of 42K’s new APEX collection of tank tops, designed to deliver maximum performance at minimum weight.
It is made with Elastter, a state-of-the-art technical fabric (88% recycled polyester and 12% spandex) developed for making high-performance garments. As well as its incredible lightness (73 grams in size M), which aids quick drying, it stands out for its extra-soft feel and its two-way stretch (the ability to stretch horizontally and vertically), which guarantees a perfect fit to the body, giving greater freedom of movement and better shape recovery after every stretch.
Thanks to the Elastter fabric, APEX T-shirts adapt dynamically to the body, reducing the chance of chafing or uncomfortable tension, which translates into optimum fit and comfort.
Its design combines elegance and dynamism with a modern aesthetic: the front features a graphic of white strokes on a sky blue background, achieved by digital sublimation, a technique that guarantees great definition and colour durability without affecting the fabric’s breathability; the back is single-colour in sky blue.
This T-shirt is ideal for intense training, middle- and long-distance competition, and for all those runners looking for an ultra-light, very comfortable technical top.
