Remaining present during yoga practice is difficult enough, so don't make it any harder on yourself by having a mat that hurts your wrists, knees, or conscience. The Eko Yoga Mat from Manduka is a comfortable, cushioned mat made of non-Amazonian natural tree rubber that's 99% latex-free and without any PVC or toxic, non-biodegradable glues, so you can stay in svanasana without stressing your joints or the environment. The closed-cell top surface is cushioned and moisture-resistant, while the grippy bottom layer prevents wandering mat syndrome and can be used as the mat surface if you need a gripper platform for difficult poses (scorpion pose, anyone?). Best of all, once your Eko reaches the end of its long life, you can dispose of it knowing that it's completely biodegradable and non-toxic, so you're leaving the smallest impact possible.
