The Avia Mat Carry tote fits most size yoga, Pilates and fitness exercise mats. It provides all the benefits of a nice yoga mat bag or tote but without a large footprint. The Avia Mat Sports Bag has a thoughtful design that features breathable side mesh siding in order to air out gym wear along with two side water bottle pockets and an interior organizer pocket for easy access to small accessories so you are not continually digging through the bottom of the bag.
