Rug storage bag. 
Light weight breathable bag so the rugs won't sweat and get smelly in storage. 
I managed to get 3 thick rugs in and 3 lites, but I'd say it would fit 4 plus, depending on size rug and thickness. 
Zip up. Has handles on both sides. Perfect for in car, storage, tack room. 
Could even use to transport half bale hay. 
Multiple purpose.
