Castelli Climber's 4.0 Jersey

The courses in the Alps in July are reserved for a few private individuals, but the products resulting from this experience are perfect for everyone. We have designed this jacket for chaotic days in the high mountains, based on the comments of the professionals. They wanted a jacket that would allow them to stay dry at all times without compromising on aerodynamics. Le maillot Climber's 4.0 Jersey reprend le positionnement de coutures CF de notre maillot Aero Race 7 Jersey, mais il est réalisé dans les tissus en maille 3D les plus aérodynamiques pour un refroidissement optimal. These tissues are also very thin and extensive, which gives this jersey a comfortable fit, indispensable for intense days on the mountain. And as this jacket is designed to be worn in the sun, we have also made sure that the fabric blocks 90% of UV rays from the front.
