You can't always count on the weather. But you can count on the Sky Fly Jacket II. Extremely lightweight, this trim-fitting rain jacket made from eco-friendly stretch fabric will disappear into your back jersey pocket, coming to your aid when rain or wind shows up. The collar can be folded out to protect the back of your neck from getting wet. A hook and loop access flap at the back of the jacket lets you get at your back jersey pocket while riding, while also helping to ventilate if necessary. Reflective stripes at the back and on the sleeves keep you safer on the road. Used in combination with Vaude's helmet rain cover, which makes a hood superfluous, it's the full anti-rain package.
