Iyengar Sticky Yoga Mat 3mm & 4.5mm With Mat Carry Strap - Blue - 3mm vs Almost Perfect PRO Yoga Mat: which is safer?

Where these two actually differ

• We flag VOC off-gassing (formaldehyde, toluene, other solvents), Bacterial and mold growth in grip surface and Surface degradation and microfiber/particle release on the Iyengar Yoga and not on the Manduka.
• We flag Volatile organic compounds (VOCs) and formaldehyde off-gassing, Natural rubber protein allergen (latex sensitivity) and Microparticle shedding from foam and rubber degradation on the Manduka and not on the Iyengar Yoga.
• The Iyengar Yoga is PVC or natural rubber base, adhesive grip surface where the Manduka is closed-cell PVC-free foam, rubber top, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Manduka is the one to buy.
