Rare Vintage MEMPHIS MANIAX XFL BIKE Full Size Football helmet.  This is one that we bought new in 2000 when they were first offered.  It has been in the factory box in a case since then.  Brand new.  These were so limited when they were distributed.  All the dealers bought the mini helmets but very few invested in the full size helmets.  It is a BIKE helmet, which was the helmets that were worn on the field and also had the licensing of the XFL at the time.  Try and find another one for sale.  Wait, try and find another one that has sold - new, in the box, complete with all of the padding and chinstrap.
