Perfect for a jog in the cool

Designed for use in conditions of relative coolness, this jacket Ultrasport has done its job. It prevents a cold snap in the first minutes of a fall or winter release, while leaving the skin breathe when the body heats up.
But obviously avoid wear in hot weather if you want to avoid the outdoor sauna. Logical since this is not its function.
For the rest, it is a rather simple design and has several well-designed pockets (including one in the chest) that let you take with you is necessary. (Do not ask too much anyway)
