Since the day of its birth, Castelli has witnessed one legend after another in the history of cycling, once synonymous with cycling clothing, although today's cycling clothing market is no longer dominated by Castelli, but Castelli is still a well-deserved leader.
 
Castelli has pioneered a number of industry firsts in the development of cycling apparel technology: the world's first Y-cut cycling pants padding, the first use of nanotechnology in cycling clothing, and the first pneumatic cycling clothing, each time leading the way in the direction of cycling clothing.
 
Relevant data show that the wind resistance during riding accounts for 75% of the total resistance, how to reduce the wind resistance as much as possible has become an important direction for the improvement of major cycling clothing brands, and Castelli is at the forefront of cycling clothing pneumatics, in a leading position in the industry. Wind tunnel test data shows that Castelli's new Sanremo Speedsuit saves an additional 90 seconds for every 60 minutes of riding at 40 km/h.
 
In order to facilitate the purchase of consumers, Castelli's official website has made a star rating for each of its cycling jerseys from the five dimensions of windproof, waterproof, warm, breathable and lightweight, and the core technology and main functions used in each cycling jersey are described in detail, and in terms of price, Castelli professional one-piece cycling jerseys are generally sold for more than $100, and the price of a single cycling jersey or cycling pants used by amateurs is between $60-80.
 
Castelli's top-of-the-line product, the Free Aero Race, is probably the most aerodynamic jumpsuit available, and is used by many of the world's top team riders. The top half of the jersey is based on the Aero Race 5.1 jersey, which has been tested in the wind tunnel to achieve the ultimate aerodynamic effect, the back waist is equipped with 3 rear pockets and heat conductive reflective strips, the front is designed with a full-length zipper for easy wearing, and the lower part is based on the Free Aero Race cycling pants, Progetto X2 top-of-the-line padding for comfort, and the compressed pneumatic design effectively reduces wind resistance.
 
Castelli was also one of the first brands to produce rain-proof cycling clothing, and the Castelli Rain or Shine is the latest update to the collection, which comes with a fake two-piece design with a base layer to keep you warm in winter. The front and back of the Castelli Rain or Shine are made of water-repellent fabric, and the nano flex xtra dry is stitched on the back to improve the breathability of the fabric while maintaining rain resistance.
