Composition and fit
The Castelli Climber's 4.0 is a masterpiece of cycling technology, made for temperatures from 22 to 40°C. Its tight fit and advanced Flusso 3D front fabric ensure optimal aerodynamics, while the StradaPro 3D back ensures superior breathability. Although not waterproof, this shirt dries at lightning speed and protects your back from more than 90% of UV rays. The elbow-length sleeves with raw cut edge and elastic waistband ensure a seamless and comfortable fit during long rides.

Extra features and finishing
The Climber's 4.0 goes a step further with its special features that enhance the riding experience. The shoulder construction is designed for maximum airflow, contributing to effective cooling. Although it has no zipp pocket, the elastic around the waist provides extra support and keeps the shirt in place. A YKK® Vislon® zip increases durability and ease of use. Moreover, by using bluesign® certified fabrics, Castelli emphasises their commitment to eco-friendliness and sustainability.
