The yogitoes Skidless Yoga Towel is an amazing product to supplement your mat when practicing a more rigorous style of yoga. This product is not an alternative to having a yoga mat, but can transform the most simple mat into an amazing surface with great traction and comfort. Having a yoga towel offers a hygienic layer between you and your mat that absorbs sweat and provides extra traction and comfort. In this respect the yogitoes Skidless Towels do an excellent job, although the Jade Microfiber Yoga Towel performs slightly better in our tests with respect to dry traction and portability.
Note that this mat is being evaluated for use in a heated yoga practice, or a more intense practice in which you plan to sweat. For restorative yoga, yoga outdoors in cooler temperatures, or other styles of yoga where you simply don't sweat, we find having a yoga towel such as this one along for the ride is simply overkill.
