Double velcro fasteners give the L.E.X.BRACE durability while in play, and allow it to be easily removed during time-outs or at the end of the game. The first fastener resides on the walls where the brace separates, allowing you to stick the brace together in the correct position before you attach the larger velcro strip (which you can see in the photo).
The L.E.X.BRACE is not physically connected to the player's shoulders or helmet. In this way, it does not constrict movement of the head, making game play easier than with other types of braces.
The inclined inner surface of the brace captures the player's helmet, making it impossible to slip out. This assures that the brace will always be effective, unlike roll-collar type neck braces which may slide out of position, greatly reducing their safety value.
The L.E.X.BRACE is covered with a smooth vinyl coating, which has a lower co-efficient of friction than traditional materials, such as fabric. What does this mean for the player? The helmet glides along the surface of the brace, rather than rubbing up against it, which would make it harder to move your head.
The brace's blade-like bottom edge results in ease of motion on the shoulder, in the uncompressed (the non-contact) state. These factors keep the brace from becoming intrusive to the player.
The high-density foam which fills the inside of the brace does the work of absorbing energy from impact and releasing it into the player's shoulders.
