Heres proof that reincarnation exists. Our new Recycled Foam Block spent its last lifetime protecting vegetables from frost. Now its sharing the spotlight with the same sturdy foam that you love in our regular Foam Blocks. Made from 50 percent recycled polyethelene film from the agriculture industry and 50 percent EVA, this block joins our Bamboo and Cork blocks as another sustainable yoga block option. This block straddles the center between the ultra lightweight Foam Blocks and heavier Cork and Bamboo blocks for lightweight, stable, comfortable support in all types of asana practice.
