What are exercise mats made of?
Exercise mats are typically made of rubber, PVC, or some incarnation of vinyl. Rubber and EVA (ethylene vinyl acetate) comprise the thicker, weightier exercise mats. The rubber is particularly great because it is usually recycled and always super-durable. For thinner, indestructible exercise mats, look for PVC. Blown PVC has a little more cushion, because it gets an injection of air. Solid PVC will be flatter and more suitable for use under an exercise machine. Roll-up exercise mats are made of all kinds of materials, but due to their portable nature, they do not last as long.
