Bontrager's RXXXL Jersey is a pro-level top in form, fit and function. The main body is crafted from ultralight, soft, breathable and compressive fabric with compression sleeves that give the jersey a second-skin fit for muscle support and superior aerodynamics. The sides and upper torso sport mesh panels for ventilation and the shoulders use thermofused Nosew seams for comfort. It also has three rear pockets and a full-length zipper.
