I think we have the best yoga mats for B-Mats grip and they are all non toxic, but still a blend of natural and synthetic rubbers. 

The ultra grippy B MAT® is B Yoga's top selling product line and the heart of the company. B MAT®s are 100% rubber giving them an inherently grippy texture, even with moisture and sweat exposure. No matter the thickness, colour or length you choose, you are sure to get stability, durability, and unprecedented grip during every yoga practice from your B MAT®.
I also am selling lots of restorative yoga props, blocks, straps, massage balls.
We also have bolsters, regular rectangle ones and the cylindrical ones.
