Input:
The Manduka Black Mat Pro is by far the most comfortable cushy Yoga Mat I've used.  Once you get it you'll know what I'm talking about.  It's thick unlike every other mat out there.  It gives just the right amount - enough to be extremely comfortable but not too much avoiding slippage.  It's a little more money than others but it will last.
