Extremely absorbent and will become more absorbent after a few washes.
What the creators of Zorb say:
"Zorb traps moisture and absorbs 10x it's weight in moisture in half a second -- that's 20x faster than cotton, bamboo or hemp knits. Zorb is also known as the best Super Absorbent Fabric in the business."
