Designed to cope with cool temperatures without compromising performance, the WEATHER VEST 1 M from ON RUNNING is a sleeveless jacket for men ideal when the weather turns for the worse.

It features lightweight On ThermaTecâ"¢insulation to keep you warm during exercise while maintaining freedom of movement during your outings. Practical and clever, its foldable design makes it easy to stow away in the double-zipped chest pocket.

Thought out down to the smallest detail, this model also focuses on comfort and safety : a brushed inner collar limits chafing, while reflective elements at the front and rear enhance your visibility when out at night or in low light.
