The side shields are a nice touch.
Yep, had me looking for the pocket protector and slide rule......
The side shields are an artifact of my last job. They were required PPE.
I got so used to them, I really hadn't thought of taking them off. It makes one less thing to worry about when I go shooting.
I never had a pocket protector, but I did used to carry a glass case with a holder for two pens and my sunglasses back in the day.
