The 3/8'' Pilates Aero Yoga Mat is extremely thick and made of soft supportive foam with a smooth surface. At 9.5 mm thick, this Pilates mat is thicker than most of the thickest yoga mats! This mat is perfect for boot camp, Pilates, or standard floor exercises like push ups and crunches. It’s thick enough to provide comfort during your tough workouts, but firm enough to provide a stable platform. When you’re ready to pack up, this Pilates Aero Yoga Mat is self-contained with two built-in Velcro straps. The Aero mat measures 72'' x 24'' x 3/8'' and is completely latex free.
