Many yoga mats come with their own towel, but you can also buy yoga mat towels separately. While they may not be necessary, there is some wisdom to using them. Yoga towels are fantastic at absorbing sweat and this is a great advantage to keep the microbes from multiplying on your mat. If you do use a yoga mat towel, you will only need to give your actual mat a quick wipe down after your workout, instead of a full wash down. Yoga mat towels also double up as a towel to pat yourself dry during exercise. Once your routine is done, the towel is easy to throw into the washing machine and be ready for use the next time.\r
