This bag is roomier than I thought it would be. In addition to my mat, I can fit my towel, a block, extra sweatshirt... Plus the outside pocket is huge. There's also a pretty good size zipped pocket for phone, keys, wallet or whatever. The zippered pocket is really the only part you can completely close up, because is it really an open style bag. So if you're in weather like snow or rain, your stuff may get wet. On the plus size, it is really easy to dig around in and get your gear in and out easily. I got the modern paisley pattern and it is really cute. The ribbon binding is a great contrast too. It seems like it will be really durable as the seams are strong and overall quality seems really good.
