The small bowel in all its glory. Its twisty shape comes from the challenges of fetal development: the growing ileum is almost too big for the abdomen and is forced to twist around to economize space. Big fish, small pond!
Adjustable straps and a flexible nosepiece help ensure a snug fit.
Outer layer: 100% polyester
Inner layer: 100% cotton
The mask can also be machine-washed and reused!
