Rapha wants cyclists to ditch the bulk on their intense winter rides so they've come up with an impressive piece of kit to keep you warm this season. The Pro Team Thermal Aerosuit features a top half that uses a wind and waterproof shell on the arms and front of the body while the back is covered in a breathable jersey fabric. The bottom half uses a sophisticated array of fabrics to help trap heat and wick away any unwanted moisture from the skin.
