I’ve been practicing yoga for about four years, most of them on a double-thick mat that I felt really smart for having found at Marshall’s for $15.  Then Amazon offered me a "Gold Box" deal on a Manduka Yoga Mat for $64 – 8% off their usual price of $70. Could a mat be worth three to four times what almsot every other sells for? The answer is yes: Yes it is heavy to carry. Yes it is expensive. Yes, it provides better cushioning and better stickiness than any ordinary mat.  If you’re taller than six feet, there’s also a longer version available.
