Product details

Our Passion Z4 cycling shorts have been revamped to offer our best shorts yet. New, lighter, and more breathable mesh straps combine with an ultra-lightweight and elastic back, providing a new level of comfort. The pieces are glued rather than sewn, and the legs are made from an improved compressive Goffrato+ fabric to ensure an aerodynamic, close-to-body fit. The 3D Endurance padding from Elastic Interface offers maximum comfort for the longest and most demanding rides.

The Passion collection combines high-quality materials, precise craftsmanship, and minimalist design in a diverse color palette. Thanks to cutting-edge technologies, a clothing line has been created that enhances your riding experience while providing a fresh, elegant look.

Your ride. Enhanced.

Mesh inserts: Elastic mesh inserts at the back of the thighs provide a better fit and increased comfort.
