giacca antivento bontrager covertible windshellThe Bontrager Convertible Windshell jacket is everyone's best friend. It's a 2 in 1 jacket. Thanks to its windproof material, it's the perfect jacket for cooler days. Besides being windproof, the material is also water repellent. It's not exactly a rain jacket, but the first drops slide off easily. Thanks to the long sleeves, not only does the body stay dry and warm longer, but so do the arms. When you get too warm, you can easily remove the sleeves
