Powerstretch is also a great choice. I literally just finished a technical cut fleece hoodie last night, made of powerstretch. It is very soft, very warm, and has great stretch. Throughout the process of making it I kept putting it on to check fit and such, and every time it was a struggle to decide to take it back off...so nice!
Now that my girlfriend has seen it and felt it she is already buttering me up to get me to make one for her too.
I haven't worn the powerstretch in the wind so I can't say how it compares to windpro, but the powerstretch is definitely more stretchy than windpro, and has that really nice looking flat outer face.
