There is no definitive packing list that fits all seasons , what to wear in Iceland depends upon when you travel.  Summer is a relative term whenit comes to Iceland, withan average July temperature around 10-13 °C (50-55 °F).  If you are very lucky, you may have a day or two with temperatures above 20 °C.  Most likely you will experaince all four seasons within a week or even a day.  Do not even contemplate taking an umbrella, it will NOT survive the wind; especially during the winter months.
