The open 3D knit miniCheck Tex provides high breathability, high elasticity, UPF 25, and the signature ASSOS jersey texture across the front. The pockets are anchored by a rear panel of Stabilizer V11, which provides hypercooling breathability and is so lightweight (UPF 15) that we recommend applying sunscreen beneath it. It also reinforces stability, preventing sag and movement when pockets are loaded. The sleeves feature the new 550CX warp-knit textile, which provides UPF 35 protection and a muscle-wrapping, bistretch fit with inherent aerodynamic properties.
