Inserting or replacing foam filler is simply a matter of dropping it into the bottom cover section. Because the top can be pulled taut even after filler loses some of its volume over time, Norbert's pits will never look loose or sloppy. Should you need the top cover section repaired or replaced, it can be removed and shipped to us inexpensively. Top cover connects to bottom section with 4" wide Hook and Loop fastener sewn on each side surface.
Design update: practice pits can now be ordered with either solid vinyl top (breather mesh sides and vinyl bottom) or breather mesh top (solid vinyl sides and bottom). please specify when ordering.
