When the air begins to nip at the tops of our ears and head, we reach for our 2/3 Robo Foil. This version is perfectly tuned for the crisp conditions encountered in spring and fall, with a midweight knit that blocks icy air and adds a touch of insulation.

Like the other accessories in our Foil family, it's constructed with the Circular Seamless technology, meaning that it's free of side seams for a comfortable feel against your head. The yarns themselves are made of polypropylene fibers that transport and evaporate moisture quicker than traditional poly blends, resulting in a breathable, hardworking cap that aids in temperature regulation by keeping your head insulated, shielded, and dry.
