I have just seen a yoga mat that costs £135. It is cork, and apparently will last me until I'm 80 and is both indestructable yet biodegradable. Any apparently I will never again slip on my sweaty mits in down dog to the point where I nearly stove my chin in.
I will not be buying it. I am not that silly.
But what's the best mat you have used, esp for hot/sweaty yoga?
