Query: Best yoga mat!

I used a Manduka Prolite when I forgot my mat one day and had to borrow one from the studio. I loved it so much I immediately bought my own! The mat is thin, but has enough cushion for me, and rolls up very easily. Also, all of the colors are beautiful, but I love the navy color that I got. It may be a bit expensive, but it is worth the investment since this mat will last forever if you care for it properly.
