Basincally, I'm using a Leatte GTX Pro Carbon and will run with no collar. The jacket is designed to hold the Leatte in place by hooking over the shoulder tabs on the brace. It has a Leatte collar too which fits over the neck brace comfortably and is Goretex. Won't be needing that in South America though.
Hope this answers the question.
I would consider bringing the collar, the stages up high in the Atacama desert get freezing cold even in the summer, literally.
Is your jacket just a blue version of the Adventure Rally 2 or is it modified somehow? I really like what I have seen of it so far, like Yeti said it looks to combine all the benefit of the AR 1 and the Badlands.
