The Pearl Izumi Select Thermal Barrier Jacket, with its light insulation and resistance to wind and water, is an ideal option for the months when the cold begins to set in, and makes for an excellent element in your layering strategy when the weather turns frigid. Select Thermal Barrier and Select Barrier fabrics provide comfort and insulation, while keeping out water and wind. A full length zipper along with an internal draft flap help to retain heat while reflective accents increase visibility in low light riding conditions.
