This vest from AGU has wind stops on the front and shoulders, while at the same time there is a bit of insulation in it.

This means that it is extremely suitable for the cold days where the temperature creeps down to between 5 and 12 degrees.

Even though there is insulation in it, it is still small and compact enough to carry in your back pocket.

There is a full-length zipper on the front and reflective details in several places.
