* It doesn't matter if you do lug around their mats. If you're in this category, then you will want a mat that is lightweight. Of course you wouldn't want to be that person who is out of breath from dragging a mat to class, right?
* With all of the sweating that occurs during a yoga session, it's no surprise absorbent materials are great for keeping your mat dry. While this is a great feature, it also means you will end up with a less than pleasant smelling and unclean mat. Also invest in a yoga mat that is easy to clean.
