Love the design of the playmat bag. You can fit two playmats in this bag
The playmat bag is a great idea. I recently attended GP Oakland and it definitely came in handy. There's enough space for you to put 2 rolled up playmats in there, maybe 3. I didn't try three. I ended up running out of space toward the end of the day and had to resort to clipping the bag to the outside of my backpack. I would definitely recommend it!
