The Rumi Sun Mat is your natural space to focus. It is engineered to be extra durable. Natural rubber sap is extracted from the bark of farm-grown trees. Only shallow incisions are made on the bark to ensure the trees have a long & healthy life. Minerals are selected from earth and added to the mix. The rubber characteristically gives you a secure grip to the floor. The top surface is designed to withstand abrasion from use. The surface does not allow any sweat to absorb into the mat. The cushioning of the mat comfortably protects your joints. After your practice, you can wipe the surface with a damp cloth that has been moistened with a natural solution of one part vinegar to twenty parts water. After living out its life as a yoga mat, if you choose to discard it, it will reintegrate back into earth within a short span. Enjoy its natural vibe!
