Named for the adverse weather conditions that exist in the Flanders region of Belgium, this base layer is designed for cyclists who don't register cold, wet, or uncomfortable. Wind-cutting and moisture-transferring front fabric allows you to ride quite comfortably with nothing more than a jersey. Ribbed main body makes for a body fit and delivers exceptional wicking abilities. Go full tuck in the back, with a dovetail hem for a little extra coverage.
