I always try to have at least 1 layer for any weather condition. So I take 1 pair of water repellent pants and coat. A sweater or 2 if I have the space. And it's always a good idea to pack a pair of shorts that you can pair with tshirts or linen shirts if its warm and sunny.
Ooohhh thats a great idea. I gues you would put in the clothes that you don't care about being wrinkled.
Can't wait to try this next time I get the change, I always pack too much and never have enough space.
