Most hated X-Metal model, but one of my favorite to wear.
Way more comfortable than the original X-Metal with their spring hinge (Penny had it too), large coverage, and most importantly no premature degradation of the nose flex, as there's none.
I actually like the Half-X for all the reasons BigCob above states but also just because of its skeletal feel. But then again I love X-Metal just because it’s X-Metal. Ha Ha.
