The Solid Block Jacket is constructed of three layer Accoppiato Termico fabric that will protect you from the cold and damp weather of autumn and winter. The exterior is a durable structured knit, while the central layer is a stretch Windtex membrane that protects from the wind but allows excellent breathability. Closer to the skin a soft and smooth hydrophilic fabric retains body heat while protecting from the cold, quickly drawing moisture away from the skin, preventing clamminess.

If you want a jacket to cover a wide range of weather conditions, keeping out the cold and repelling all but the heaviest of rain, then this versatile Solid Block Jacket is a great choice.
