Testimonials

Rui Gomes

BREAK

"This product is a pleasant surprise. In my opinion, it brings together three essential components: a simple yet effective design, the elasticity and comfort of the materials used, and finally, the finish that ensures top performance. The integrated belt makes it suitable for both race day and outdoor training, carrying all the essentials. It’s definitely a great choice for those looking for a minimalist or competitive trail experience."

Patrícia Silva

BREAK

"The shirt features a breathable, ultra-light, adjustable, and super comfortable fabric — ideal for maintaining body temperature and maximizing performance. You barely notice the integrated belt, no matter how much you carry in it. Thanks to its ergonomic fit, there’s no discomfort: it fits a 0.5L flask, phone, keys, gels, and bars."
