Who even designs period pants and night pads?!

I can't be the only one who wakes in the night to find that the blood has completely bypassed the gusset region and landed somewhere around the sacrum or sometimes beyond, closer to the waistband?

The only thing saving my mattress is disposable incontinence pants, which now all stink like petrol/chemicals, including Tena, so I don't really want to use those anymore.

Has anyone found a solution that covers the whole area but doesn't contain PFAS, silver or stink to high heaven of toxic sludge?
