I have the Traverse jacket in subalpine, no experience with the Ambient.  Really like the jacket, wear it a lot, up until the temps drop in late October/early November.  Once the leaves are down and it gets colder, switch over to my heavier stuff in open country - elevated II patterns.  (Hunting whitetails in N Georgia). Properly layered, the Traverse is fine down to the upper 30s. (Stationary from a stand).  I don't bowhunt much anymore, but the fabric is fairly quiet.
I am 6'3" and weigh 200. The XL fits well, leaves room in the torso for layering.
