A
Zen yoga mat is an alternative to a traditional sticky mat. It is
made of cotton, but once it is a little damp from perspiration it
will not slip. In India it is common to spray a little water at the
head and feet position at the start of practice to prevent slipping.
A Zen yoga mat is typically made of organic cotton. Look for mats
that are toxin and pesticide-free and are "fair trade."
Usually this will be specified on the Web site.
If using an organic Zen yoga mat didn't seem eco-friendly enough
to you, there is now an even more environmentally sound option. Some
manufacturers are introducing a biodegradable mat. Some suggest this
may be just a marketing ploy, but to others it calls to mind how yoga
and Zen teach practices that mirror the cycles of life.
