Same iconic Chub Rubs. Even kinder to the planet. Castor Oil Stay Cool Chub Rubs® in Black are made using yarn derived from the castor oil plant, a hardy crop that thrives in poor, drought-prone soil and helps farming communities grow a meaningful, sustainable livelihood. These plants grow on land that can't support food crops, require very little water, and actively absorb CO2 as they grow, making them a brilliant renewable source for high-performance yarn. This makes a fabric that performs exactly like your favorite Chub Rubs - silky soft, breathable, stretchy, and gloriously cooling - but with a lower environmental footprint. So you get the same thigh-saving magic you know and love, with a little extra feel-good factor woven in.
