Over the weekend I made the trip to an REI to check out the patagonia R1. It was thew first time I was able to see one in person and try it on. The hoody was all they had in stock, which got me thinking. If I would purchase an r1, would a hoody or the jacket be a better choice? I would think a hoody would fit better in a layering system but the jacket would be better at regulating body temperature (by having the option of unzippering it)

Thoughts?
