I am just starting my yoga journey. Wanted a mat that the grips weren't lumpy, this is perfect. I like the guidelines too. Just a comment about the packaging - sent in a massive square box, with 72 (yes I counted them, as I couldn't believe it!) of the air-sacks. The mat came in its own black carry bag, with another string strap. Very happy with this purchase, just not the wasteful packing!
