The new Alum layer long-sleeved pullover from Sunice does exactly what it says on the tin. It is a piece of clothing that can be worn as a mid or a top layer depending on weather conditions. It is highly breathable which means that you will remain warm, dry and comfortable. It comes with a half-zip design up to a high neck so warmth is retained. This also allows you to remove or put on the top at a moments notice should the weather change.
