Introducing the UCI legal PRO8 Base Layer Optimised Using many of the same materials and aero tech as the PRO8, the Base Layer Optimised suit has been specifically developed as its name suggests, to be used with a base layer. When tested against major competitors, all using aero base layers, this suit came out on top! Up to 21 watts faster at 55km/h and 5 degrees of Yaw, This suit does not include a base layer, and is merely optimised for those produced by other brands. Our testing recommends the HUUB baselayer to be the fastest when paired with this suit.
