M Frame vs Radar Frame size

[BigMikeFromOleMiss]

How does the size of Radars compare to M Frame's size? I have a big head and Normally wear Fuel Cells, but I have worn M Frames in the past. I am curious about Radars.

Forgive me if this is answered some where. I tried to search it first.

I have been wearing M frames since dinosaurs ruled the earth, and find they fit my 7-3/8 hat-head comfortably. My Radars fit only slightly tighter but still quite nicely.

Considering how closely related they are, they have very different fits.

The Radar certainly has more rigidity as the frame is wider. For me it feels more "closed in" vs. the M Frame that just feels open.

I find Fuel Cells too small, but wear M Frames and Radars without issue (or maybe that's just in my head?) As long as you stick to the bigger lenses - Pitch and Range for Radars, Hybrid, Strike, Heater for M Frame.
