Inspired by the biting cold of Belgium in February, the Flanders Warm Baselayer is a winter masterpiece that wraps you in high-loft, ultrasoft fleece and multi-denier fabric that wicks sweat to keep you dry, no matter how hard you push. A mid-height neck, extended back, and long sleeves seal out drafts, with mesh armpits for added breathability. Designed to layer tightly under a shell or jersey (size up for a roomier fit). Whether you’re dreaming of riding cobbled Belgian classics or in your own backyard this winter, this is Flemish-level artistry in fabric, built for riders who defy winter.
