Castelli Beta ROS Jacket

Autumn and spring are fabulous times to ride a bike. But the weather is so hard to predict and achieving the right balance of warmth, breathability and weather protection is difficult - you'll often end up too warm or too cold. However, the Beta ROS Jacket makes it easy. Using a mix of lightweight and stretchy fabrics it cuts out most of the wind, remains extremely breathable and should rain strike offers surprisingly good water protection.

Facing into the weather, the front panels and upper sleeves use Polartec® NeoShell®. This is windproof, waterproof and breathable, striking the balance you need when the weather changes from good to bad from one moment to the next. Across the back Castelli use their Nano Flex Light woven fabric. This prioritises breathability, keeping you dry and sweat-free when you're pushing hard on the pedals or the day warms up. It is also windproof and splashproof, for all-ride comfort. 

Castelli tailors the Beta with a race-bred fit, perfect for fast autumn and spring rides and smooth efficiency when tackling rolling terrain. No flapping fabric to sap energy, leaving more watts for the job at hand, riding and training hard. When it comes to features there's nothing unnecessary either. Three rear pockets offer space for nutrition and spares, a reflective panel keeps visibility up during evening training sessions and a full-length front zip makes it quick and easy to control ventilation.
