Castelli Thermal Block Long Sleeve Jersey

Smart style meets performance technology in the Castelli Thermal Block Long Sleeve Jersey. Warmer fabric makes up the front and back panel and helps to retain heat while effectively wicking moisture, while the sleeves and sides are engineered from Warmer X-Stretch, a more stretchy material that still brings light insulation. 

Gripper elastic inside the waist hem holds the garment securely in place and to the back are three open pockets providing ample storage. The full front zip, covered to create a further barrier to the elements, can be quickly unzipped as and when you need a blast of fresh air. Finished with reflective elements, this jersey is well suited to riding in low light conditions and after dark. 


  • Warmer fabric on body

  • Gripper elastic at waist
  • Three open rear pockets
  • Reflective viz strips for visibility
