The Assos Equipe RS S11 Jersey features is the innovative open 3D knit miniCheck Tex fabric that covers the front of the jersey. This material is known for its exceptional breathability and elasticity, providing riders with a comfortable fit that adapts dynamically to their movements. It boasts a UPF 25 rating, ensuring substantial protection against the sun's harmful UV rays while maintaining the signature ASSOS texture that aficionados have come to expect. Further enhancing the jersey's functionality is the rear panel made of Stabilizer V11 fabric. This ultra-lightweight material not only offers hyper-cooling breathability with a UPF 15 rating but also reinforces the structure of the jersey. It ensures that the pockets remain stable and don't sag or shift, even when fully loaded, making it an essential feature for long rides where carrying capacity is critical.

The sleeves of the jersey are crafted from the newly developed 550CX warp-knit textile. This fabric provides UPF 35 sun protection and features a bistretch, muscle-wrapping fit that enhances aerodynamics and supports the cyclist's muscles during intense efforts. Assos' racingFit silhouette rounds out the jersey’s design, offering a second-skin feel that's both aerodynamic and exceptionally comfortable. Developed with input from World Tour athletes and tested in the world's most demanding races, this fit utilizes compressive textiles and micro-adjusted shaping to reduce drag and increase performance efficiency. The low-bulk, raw-cut hems and cuffs further streamline the fit, reducing unnecessary fabric and focusing on speed.
