Castelli Sigma Sports Competizione 4 Jersey

Castelli x Sigma Competizione 4 Jersey

Finding a cycling top that balances race-day performance with all-day comfort can be a challenge, but the Castelli x Sigma Competizione 4 Jersey bridges the gap flawlessly. Crafted as the quintessential all-round jersey, it is just as suited for high-tempo chain gangs and fast group rides as it is for long, steady training miles. At its core is the advanced Strada micromesh, ventilated stretch fabric, which actively pulls moisture away from your skin to keep you cool and dry as the summer temperature rises. Thanks to its super-stretchy construction, the jersey offers a tailored, aerodynamic fit that contours naturally to your body shape, providing a sleek profile without ever feeling restrictive or overly tight.

Every detail of this collaborative jersey has been meticulously considered to give confidence on the road. The raw-cut sleeve endings create a smooth, second-skin transition against your arms to reduce drag, while the silicone gripper elastic at the waist ensures everything stays securely in place when you're tucked in the drops. Practicality matches performance with a smooth, full-length YKK® Vislon® zipper for effortless temperature control on tough climbs, alongside three traditional rear pockets and a fourth zippered security pocket to keep your valuables safe.
