Product details
The SI2 pants 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 bike pants 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 pants offer excellent freedom of movement and are up to 40% lighter than their predecessor version. Reinforced inserts in the knee area increase abrasion resistance, while the cut of the pants is optimally tailored to the rider's body line. Laser-cut openings on the inner thighs provide 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, making the pants ideal for various weather conditions. The SI2 pants are available in sizes for children and adults and feature a micrometric closure and Velcro adjustment options to accommodate all body shapes.
