Castelli Mortirolo 4 Jacket
Castelli Mortirolo 4 Jacket
Perfect for use on dry, cold days, the Castelli Mortirolo 4 Jacket is a great addition to any winter training cyclist's wardrobe. If long rides are your forte, then this is ideal and if you’re a lover of high-intensity efforts, then it is too. Any type of riding you undertake, this jacket can handle it.
Constructed with a Gore Windstopper X-Fast fabric on the front, the jacket is windproof and water-resistant for a much more comfortable ride in cold conditions. The back comprises of a breathable fabric that keeps you dry when you’re putting down the power but allows enough warmth to stay trapped amongst the back thanks to its silicone grippers at the waist. These grippers stop the jacket from riding up, protecting you from irritating road spray that can leave you wet and cold.
The front zippered chest vents further enhance the breathability and ventilation of the Mortirolo 4 Jacket. If you’re serious about your training rides, then you may start to heat up over time thanks to the vast amount of layers you’re wearing, but with to these vents any excess hot air can be let out to cool you down.
Three external rear pockets offer enough storage space for all your spares and on-the-bike nutrition, whilst a reflective strip on the back increases visibility in low light conditions.
