Have you had a chance to see the yoga mat that Ecohaus just added to their product catalog?
These mats are exactly what you're looking for. Have a look... EcoWise Fitness Mat
You don't have to pay a fortune. Offered a few places online that the brand is called Earthly Fitness. I'ts made from closed cell foam material and is Latex, PVC, Phthalates, and Chloride free. Comes in four colors - pink, green, purple and blue. Hard to find all that for one under $50.
Testimonials:
These mats are fantastic -- I want to order more and I can't wait until they offer additional colors!
I've been waiting for the EcoWise Fitness Mat for some time. I'm just fed up with the level of chloride in other mats on the market!
