* Important Note: We highly recommend the Natural Sand/Silver yoga mats over the Official Red/Black.  Because the 50-year-old Horween Tanned-in-Tack football leather maximizes grip by not sealing with a top coat, the official football red leather is *not* colorfast and bleeds when wet or exposed to heat and humidity.  We recommend dark clothing with use.  We continue to make Official Red Yoga Mats for dye-hard football fans who aren't afraid of a red skin practice.
