Fair enough.
I find that wind going through helps a lot at high temps. I believe it's the main reason why my jacket is comfy. It's the kind of waterproof breathable jacket that do well in warm weather but let too much cold wind go through in colder weather. When it's not too hot a WPB that is windproof can certainly do as good if not better.
