Perfect for home or studio use, these lightweight mats provide the cushioning your body needs to enhance proper alignment and maintain poses. Your hands and feet will love the stability that the light-tack non-slip texture brings to your practice. Manufactured free of the top six most harmful phthalates, this mat is a healthier choice for both you and the planet! Please note a packaging change from 3mm or 4mm, but rest assured it is the same size and style mat, just in new and improved packaging. Also, printed yoga mats may release a harmless odor when first unwrapped. For best results unroll and air out your mat for 2-3 days before use.
