Care to elaborate? I got an ultra in today that I bought in the classifieds last week, holy smokes is that thing thin!
After freezing my butt off on the side of a mountain sheep hunting I came home and got the Pro. Well worth the money. I can sit in the pro down suit and glass for hours in below freezing temps. Not so much with the ultra. The ultra would be good if you were moving around in cold temps. It’s not great for sitting and glassing.
