You won't waste time scrubbing your mat again! Closed Cell mats offer superior sweat resistance. By not absorbing your sweat, this mat won't deteriorate as quickly as its porous, open cell competitors. The difference is clear. Open cell mats are porous and absorb sweat, dirt, and bacteria. With the added moisture, open cell mats break down quickly and literally deteriorate before your eyes in the middle of your yoga practice. The closed cell technology of this mat, combined with its smooth surface makes it easy to clean, sweat resistant, and ultra long lasting. By wicking away sweat and moisture, this mat stays cleaner, and dryer than other mats, making it one of the best and most durable mats on the market. All this and Eco-friendly too! Made without toxic chemicals in production, this product is latex free, rubber free, and hypoallergenic.
