Look for a cork mat. For your steamier asana endeavors, the pros suggest keeping two major factors in mind when selecting a mat—grip and cleanliness. According to Chris Willey, founder of Yoloha Yoga, cork is superior to other materials in the hot room thanks to its antimicrobial and insulating properties. “Cork doesn’t actually absorb water,” he says. Instead, when the material gets wet, it releases a waxy substance called suberin that gives the material its non-slip quality.
Alternatively, a rubber mat is still a good option depending on what it’s made of, according to Dean Jerrehian, president of Jade Yoga. “We have found that natural rubber is ideal for hot yoga because of the grip provided when wet with perspiration.” He also notes that for particularly sweaty classes, it’s not a bad idea to keep a towel on hand.
