BW,
I am appreciating your help here !
I think we are seeing things much the same.
I have also looked at the guide jacket vs the Jetstream.
Guide doesn’t have windstopper. So I’m guessing it’s more breathable , but not quite as warm. This might make it slightly better for an active jacket whereas the Jetstream might be better suited for a static jacket.
What is your take on the Jetstream vs guide ?
