Product Description

sst sizing chart

Fitted inside the hat providing coverage from the side of the logo / bill of the hat to behind the ear.  Right handed pitchers insert the guard on the right side of the hat and left handed pitchers insert the guard on the left side of the hat.


Each SST Pro X Performance Guard has an approximate thickness of 1/5″ and weighs approximately 2.2 ounces.  Important: A larger hat size may be required with use to maintain a proper level of comfort.  However, the vast majority of players can their existing hat size.

SST Pro X Performance Guards are unlike any other padded cap for pitchers, only covering the most at-risk area of a pitcher’s head.  This allows the pitcher to wear concealed head protection without any physical or mental distraction.  When used with a properly sized hat, the guard is virtually unnoticeable.

The SST Pro X Performance Guard for Pitchers is designed for optimal energy dispersion in the event of a batted ball impact.  The inside of the SST Head Protection Guard is lined with a high density polyurethane padding for added comfort and protection.


All SST Products have been put through a battery of impact tests ranging from 60-93 MPH.  Using a headform, triaxial accelerometer, and launcher, we were able to determine a very tangible difference in G Forces when impacted with and without the SST Head Guard.

    Wanted to let you know that my son starting wearing your product yesterday at his game that he was
    pitching in. My son stated after the game that he didn’t mind wearing it and he didn’t feel any difference on his head. As a parent
    of a ballplayer that is my worse fear is seeing my son getting seriously hurt playing that game that he loves.
    Thank you for the product I really wish more people would wear them in games.
