Merrithew’s signature mat for all CORE™ conditioning exercises, the Express Mat is lightweight, super-cushy and made of durable closed-cell NBR foam 10 mm (0.4″) thickness. Protect your spine from hard surfaces, while keeping comfortable as you exercise. To accommodate many different exercises and surfaces the Pilates Express Mat has ribs on one side and is smooth on the other. As with all Express Mats, the integrated Velcro straps allow you to roll up the mat and go! Includes downloadable BONUS Exercise Guide.
