The hottest days of the year are approaching, but that shouldn’t stop you from pedaling. Get prepared to conquer the heat on your summer rides? Our Climber’s Jersey is here to save the day.
Cool, Fast, and Light
Designed for performance on the hottest mountainous days, our Climber’s Jersey prioritizes low weight and temperature regulation. Weighing just 118 grams, it's also remarkably aerodynamic, thanks to CFD-based seaming and wind-tunnel selected fabrics that keep you dry and cool.
High-Performance Design
Whether you're pushing hard to steep climb or putting down the power along the valley, the Climber’s Jersey excels. The key to this jersey is in the fabrics and construction, optimizing aerodynamic efficiency. This design approach ensures cyclists maintain their speed and reduce air resistance, even in extreme heat.
Stay Comfortable and Protected
Tired of overheating, sticky clothes, and the fear of sunburn? With this Jersey you can leave those worries behind. Thanks to the UV protection it allows ample airflow, is quick to dry, and blocks more than 90% of UV rays on your back.
