While most people consider winter their off-season from cycling, you and your fat bike beg to differ. When you're suiting up to break trail over a fresh coating of white stuff, start your layering with the 2002 Top Jersey. This sleek, form-fitting base layer is constructed with Drytex 2002 fabric, a lightweight synthetic that uses Nano-Silver fibers to help regulate temperature and resist odor. The hollow fibers pull moisture away from your skin rapidly while you grind it out on loose, snowy trails, helping you stay dry and cool when you're putting forth serious effort in cold temps. With its mock neck design, the top prevents cold air from sneaking in next to your chest and sits more smoothly under other other layers.
