Going make a manga about getting swallow alive by giantess but not digest or burn to death in stomach acid?

Hi guys i am one of the weird artist as karbo from the felary manga. I going create a non violence giantess. But gentle Giantess. As giantess when they get hungry they gonna eat something fresh or swallow in bite size. But i was pondering if i was the victim of the giantess and my height is around 3cm or 5cm and getting swallow by giantess is there idea what kind of suite or armor can withstand stomach acid and small intestine. Give some idea and point i be very appreciate it.
