Walking in mid May

I hate/feel the cold and have walked separate caminos at diffeent times of year-including high summer and was always glad of my sleeping bag-Snugpak travelite 900gr. Even with that I sometimes slept with a blanket or in my clothes. The point being that you need a decent sleep which you won't get if you're shivering all night. I don;t take a coat as such but rather 1 t shirt which can be worn under a shirt and a fleece (lightweight but warm)-or variations depending on the weather.I used to take flimsy ponchos but decided after 2 disastrous caminos with them I now have a very efficient (but 800gr) 3/4 length rain coat-this could also double up to keep me warm. So with those 4 items I am well prepared. Don't bother asking about weather-it's unpredictable! The people in the albergue at castro dozon who did'nt have a blanket in addition to their sleeping bags shivered all night...and that was late june.
