Rapha hit the drawing board to come up with the most race ready, technical jacket out there and the end result of all that extensive R&D is the new Pro Team Softshell jacket. The jacket was designed to perform in the wettest conditions without being too constricting.
Using a two thin layers that sandwich a membrane, the jacket is breathable, water-resistant, and warm. It's also got fully taped seams to lock the water out and laser cut perforation under the arms increases air flow throughout your body. The jacket is available in limited quantities at Rapha.cc ($295).
