For the latest largest exercise mat here is the bag you need to roll it in. Outside pocket for keys or phone. Throw it over your shoulder and go.

These were made specifically to fit Kulae Ecomat Ultra 72" x 24" x 8mm

Mix and match fabric, pockets and straps if you want to create your own version i'm happy to sew it up! These are also available on etsy, see link above to get there!
