I spent a lot on the Namastay mat because I wanted to make sure that I didn't have to buy a new one for years. What happened instead: at the beginning the mat was very slippery on the top, no grip during practice. It came with zero instructions as to how to clean it or anything else. After a while the top grip improved but guess what: 6 months in there was ZERO grip on the bottom, i. E. while my hands & feet don't slip, the mat is not gripping the floor AT ALL which makes certain poses impossible if not dangerous. Not buying lululemon again.
