Designed to last a lifetime (or two), Manuka PRO series yoga mats curb the amount of PVC mats that enter landfills every year and reduces overall mat consumption (check out our Lifetime ). During the manufacturing of most PVC products, toxic emissions may be released into the air. However, PRO series mats are manufactured through a process that ensures no toxic emissions are released into the atmosphere. The Manuka PRO is certified safe for human contact by OEKO-TEX*, a material certification agency in Europe for the textile industry.
