Hope the XS works out. If not, I’ll research the XX because I know nothing about it.Its one of those pairs that either works or it doesn't. Put them on and go driving. If you start getting a headache before you get home you will know for sure. That is what happened to me. I love the style and could pull off the square look with my younger face but I am now down to two pair after the grim realization I aged out of them. If you find yourself in the same boat with the comfort of them look at the XX model if you still want a large eyepiece. More expensive and sell fast when offered usually but very comfortable on a wide head. If you are patient you can still pick up an XX for $450 to $500.
