Hi all,
I just got back home from the Portuguese route. I only had a liner with me, but some Albergues didn't have blankets so it was a bit cold (you can sleep in your cloths but it will still be cold). Some nice fellow pilgrims borrowed me their sleeping bag so I was fine, but I would take a summer sleeping bag (or a small and light blanket) next time.
As for shoes, I had hiking boots and flip flops at first but got blisters between my toes exactly where the flip flops were putting pressure on my skin, so I bought shower shoes instead which were much more comfortable and served me as sandals during breaks and in the evenings.
For clothing, I had 1pair of long pants, one 3/4 and one short which was a good mix.
I had 3 shirts and 1 long sleeve shirt plus a rain jacket. Next time ill take a second long sleeve shirt cause it gets cold in the evenings. And you might want to wash it at some point.
Generally: Take less rather than more. You can buy things you need along the way.
I asked a friend to help me select things I didnt need before and was quite happy with what I brought.
My total bag weight was 5.6kg without food&water so I must have done something right
. Still I had things with me I didn't really need.
Hope this helps a bit.
Mira
