Polyvinyl Chloride (PVC) is a hard plastic that requires harsh chemical softeners, such as phthalates, to make it appropriate for use in soft plastic baby items such as bibs. In 2003 we discovered that certain phthalates were shown to disrupt reproductive functions and cause other developmental problems, so we launched a line of PVC-free items. Not only are these yoga mats PVC free, but they are also formamide free. We know that lugging around everything parents need for their little ones can be a real chore. We have a collection of items to make life simpler when on-the-go.
