With the Competizione shorts, professional-level Castelli quality doesn't have to come with a professional price tag. Competizione is equipped with almost the same technologies as their more expensive offerings such as the KISS Air2 insert and Giro4 leg grips which makes it convenient for both long-term and for short trips. The main panels use Vortex fabric from Castelli providing optimal breathability and comfort and the inside of the legs is made of thicker lycra for better compression stretch and rebound due to which more movements occur when pedaling. Perforated KISS Air2 padding and seamless upper circulate cool air through the shorts , providing you with comfort on your bike.
