Manduka Black Mat Pro
The Manduka Black Mat Pro ($129) is thick and extremely dense so it protects your bones and joints from pressing into the floor. It will last forever and comes with a lifetime guarantee. Since it's so durable, it's perfect if you practice most or all days of the week. If you sweat a lot, this mat gets dangerously slick, so place a nonslip mat towel ($40) over it.
