I made my pilgrimage in May/June a couple of years ago. While it was generally clement weather, I found the mornings cold for the first hour or so and there were a few cold days. What really helped me out was taking a thermal long sleeved rash vest that I use for surfing. These are far lighter and take up a lot less space than a normal jumper or sweashirt and keep you exceptionally warm. You can pick them up for £20-£30. I hope someone finds this useful.
Anyone else got space saving/unusual tips for keeping cosy?
