Abstract
Various embodiments for a panel that may be combined with other similar panels to form a padding layer of an athletic field, or other surface, are disclosed. The panel for use in a padding layer of a panel system includes a male locking element configured to form a dove-tail connection with at least one adjacent panel. The dove-tail connection includes a male locking element of the panel coupling with a female locking element of the at least one adjacent panel and forming an interference fit between the male locking element and the female locking element. A space is proved between the male locking element and the female element when coupled that permits thermal expansion of the panel.
