The Surface Pilot Fortified Suit, or "Fortified Suit", is the standard pilot suit of all pilots operating TSFs, designed to protect all pilots from the risks and rigors of piloting a TSF. Its midsection is made of a reactive material that hardens upon detecting a sudden shock or blow, and a strong neck brace protects pilots from suffering neck injuries during high-G maneuvers. The entire suit is locked into the pilot seat via two locking bolts at the lower back and four more in the suit's lower leg regions.
