Racoon Outdoors summer and transition jackets differ, just like the seasons. The summer months tend to be warm, whereas spring and autumn can be a little chilly. The need for outdoor clothes changes according to the weather, which is why we have made both a summer jacket and a transition jacket. The difference is that the summer jacket has a light cotton lining, and the transition jacket has a warm fleece lining. Both summer and transition jackets are water and windproof.
