Kabin fits a wide variety of head shapes, but is designed for a medium/large face, so if you head fits that size description, you'll probably be happy with the Kabin model! Larger Kaenon models include Klay, Hard Kore and Lewi
If you need a specific measurement, feel free to email the Kaenon Polarized customer service department with your questions at firstname.lastname@example.org
The Rhino aren't quite as "bulky" as the Gauge, so a hat should fit better with these. Brian Gay, a PGA Tour pro, wears Jetty, which has a fairly similar shape as the Rhino and he wears a hat/visor with them just fine. The temple tips taper down on these more than the Gauge do, so that will also help. Still the same great SR-91 polarized lenses.
