Evolve SI2

Product details
The SI2 bike shorts from Evolve are the result of an intensive development phase lasting over a year and a half, in collaboration with elite rider Michael Bias. These shorts are specifically designed for BMX racing and mountain biking, combining performance, protection, durability, and comfort in a thoughtful design. Made from an innovative, four-way stretch material, the SI2 shorts offer optimal freedom of movement and are up to 40% lighter than their predecessor. Reinforced inserts in the knee area increase abrasion resistance, while the cut of the shorts is perfectly tailored to the rider's body line. Laser-cut openings on the inner thighs ensure constant ventilation, and the ultra-breathable fabric on the back of the legs adds to the comfort. A water-repellent coating protects against splashes, moisture, and dust. The SI2 shorts are available in various sizes for children and adults and allow for easy attachment of protectors.
