Input:
This is a wonderful yoga mat.  I practice yoga 2-3 times a week and previously had a mat that I purchased from a local department type store; which started to crumble after about a month of use.  I researched quite a bit and found the Manduka series of mats.  I have been so pleased with my purchase.  There is no slipping with this mat and I feel like my yoga practice has gotten that much better. I would recommend this mat to anyone
