These extra large (30 in. tall and 12 in. wide) yoga mat bags are made out of the empty water sacs that litter the streets of Port au Prince and eventually wind up polluting the ocean. Jobs are created for those who collect these bags and turn them into these amazing yoga mat bags. They are large and strong enough for any yoga mat size and will have room left over for a towel, water bottle, and anything else you want to take with you to yoga class.
