The Prana Synergy Towel Mat is perfect for those who are ready and willing to suffer in peace during Hot Yoga. It may be over one-hundred degrees in the studio and you may have lost more liquid than you thought even possible, but while using the Synergy Towel Mat you stand strong in your poses while everyone around you seems to be slipping about on their mat. Prana fused the best of both worlds with this towel mat--an absorbent top soaks up your sweat and gives you traction while a rubber bottom keeps your mat towel in place on or off a thicker mat. You won't feel like your arms are going to just slip out from under you while sweating out the downward dog pose with the Prana Synergy Towel Mat underneath you. Well, at least not from mat slickness.
