Retrax
I did not invent Retrax, but the moment I played with one, I fell in love with it and have worn one every day since.
Whether I am Shooting, Training or Fishing, the Retrax keeps my eye protection locked firmly to my hat, head or neck.
The design is similar to a window blind. Simply pull to lengthen and lock, and pull again to tighten or adjust. It gives me “Tactical” options and prevents snags or damage and loss of expensive eyewear. (which I am an expert in)
