If the weather looks like it could turn at any minute, throwing on a convertible jacket is the answer.
One minute it's a wind- and water-repellent jacket that protects you from showers. Take off the sleeves, though, and it becomes a gilet that keeps your core warm in windy weather.
- Get a 2-in-1 running jacket and gilet
- Change between a jacket and gilet on the go (you can easily store the sleeves in the pocket)
- Stash your keys in the handy pocket on the sleeve
- Focus on your run with noiseless ripstop woven fabric
