Castelli Go W Jacket

The Go Jacket is Castelli's most versatile jacket. It can be used as a lightweight shell in mild conditions or in colder weather when layered with insulating garments underneath. Stretchy, comfortable, breathable, windproof, water-repellent, stylish, and lightweight – this jacket has it all. It is made from the lightest Gore-Tex Infinitum Windstopper three-layer stretch material, which is excellent for milder conditions, and the stretch provides a fantastic fit. It features the same outer material as the Alpha RoS 2 Jacket, which has been described by Cyclingnews.com as the benchmark for the performance of good winter jackets. However, the Go Jacket forgoes the integrated lining of the Alpha, allowing you to decide how much insulation you need. Add a Flanders Warm base layer and a thermal jersey to extend the comfort range to temperatures below freezing. On the back, there are three pockets with a large reflective strip that runs across the entire bottom of the pockets, ensuring visibility at night.
