So I got the Manduka eKO mat after doing lots and lots of research on yoga mats. I've been getting serious with my yoga, so I wanted a mat that would last and provide me with the grip that I need. Please note that this mat is probably one of the heaviest mats out there (unless we are talking about the Manduka Black Mat, which is heavier), but it's totally worth it. It feels like a thin mat, but it's really cushy and supportive. I will admit that the strong rubber smell got to me at first, but after hanging it outside for more than a week and wiping it down with a mixture of water and apple cider vinegar (1 to 1 ratio), the smell is bearable and getting much better. Please note that there is a correct "side" to the mat. The side with the frog on the label (the side that is all rubbery) is the correct side. I've seen other people use the wrong side before, and I don't understand how they can stand it because that side has no grip. The side with the frog on the label will provide you with incredible grip. I sweat a lot and would always slip on my old mat. I have not slipped yet on this Manduka mat and hopefully, it will last me a long time! Namaste!
