The result is a glove that beats the competition in laundering nearly three-to-one, and absorbs almost twice as much oil and grease while still delivering a sure grip. What's more, Zorb-IT doesn't delaminate after only a few washes, standing up to repeated washings with no shrinkage. Zorb-IT's revolutionary design is what you've come to expect from the worldwide leader in hand protection technology.
