This thin wind and splash barrier provides a surprising amount of warmth while being so light and stretchy you'll hardly notice it. Its race fit is engineered for performance on fast autumn and spring rides, excelling on any terrain you choose to conquer.The Beta RoS (Rain or Shine) jacket is the ultimate solution for high-intensity riding in cool and damp conditions. Its intelligent construction utilizes advanced `Synthetic` fabrics to create a microclimate around your body. The front and upper sleeves feature a `Windproof` and `Waterproof` membrane that shields your core from chilling winds and sudden downpours, ensuring your comfort and focus remain unbroken. This targeted protection is essential for maintaining core temperature without the bulk of a traditional winter jacket, making it an indispensable piece of `Thermal` gear for transitional weather.Performance is nothing without comfort. The Beta RoS jacket is built with exceptional 4-way `Stretch` fabric throughout, allowing for a close-to-body, aerodynamic fit that moves with you, never against you. This eliminates flapping fabric that can slow you down, providing a silent, efficient ride. While the front panels block the elements, the back is crafted from a highly breathable fabric that excels at wicking moisture away, preventing overheating during intense efforts and steep climbs. This dual-fabric approach ensures you stay dry from the inside out. Practical details, like the three spacious rear pockets, provide ample room for essentials, while the easy-sliding YKK® Vislon® zipper allows for instant ventilation adjustments on the fly.
