Multiple layers taking on and off is a pain point when running outdoors. It is too cold if you have no jacket on in the beginning and nowhere to place or store when the body is overheated when you need to take off your 'shell'.

It will be more convenient if we take just one(layer) jacket when running outdoors and keep it on our body when it could both keep the body warm as well as drop the temperature fast when we are too hot.

Solution: A premium waterproof with an adjustable ventilation system that could manage thermal control. The jacket features an integrated storage belt to hold belongings and mitigate them from bouncing.
