He's just got a fat head. (TWSS)
R1s are big, relatively speaking. They even made thicker t-shox options for them to make up for that.
R2 is also a very comfortable pair, better suited for larger heads than many of the other x-metal options.
That's why I recommended those two after you shared your earlier experiences.
What is "TWSS"?
I can stomach the R1 design, but can't get into the R2's. There is just something about the little tail on the lenses that keeps me away.
I did appreciate the recommendations though!
