Cannondale is well known for its obsession for R& D and this goes as much for its clothing as its bikes. The Midweight jersey uses its Channel Tex polyester/Spandex mix (92/8 percent mix) to produce a wicking jersey that is both form fitting, without being so clingy that you feel shrink wrapped.
We found the jersey worked best with a thin base layer because it's quite warm and doesn't need much of an insulator as it gets colder. The triple rear pockets are mid-depth and feature a run of reflective piping to help drivers see you on those darker winter rides, and a zip park stops you're chin from getting rubbed by the zip. Another feature we like is the silicon gripper that stops the jersey from moving about, especially useful if you're wearing a hydration pack, which can make this happen.
