About this Item
WARM AND BREATHABLE: Made of warm brushed Andorra material, this jersey provides comfort and insulation while allowing for breathability, making it the perfect choice to keep you riding through Autumn, winter and spring. Whether you're on the road, gravel, or mountain biking.
LONG SLEEVES: The sleeves are designed for both elegance and functionality, ensuring a tight fit, added warmth, and reduced wind resistance. The sleeves are also made of an elastic smooth material to fit every body type.
LIGHTWEIGHT AND STRETCHY: Made of weft-knitted polyester material, this jersey is lightweight, stretchy, and breathable, making it ideal for cold weather cycling. The two-layer structure made from lightweight fabrics with the reverse side from special microfiber effectively transfers sweat to the top layer.
REFLECTIVE TABS: Reflective elements are positioned on both sides of the rear pocket for increased visibility, making you more visible on the road, especially in low-light conditions.
SILICONE WAISTBAND: A silicone waistband helps keep your jersey in place and prevents it from riding up while you're cycling, allowing you to focus on your ride and enjoy the journey. The waistband is also highly elastic and provides a secure fit.
