I love this purchase! My Gaiam bag holds my Jade Harmony mat and the size is perfect but if you're wondering if it has enough room to wiggle a bigger mat in, the answer is yes. Your Manduka Pro will fit since it's velcro adjustable inside so you definitely have ample space to work on. The outside pocket is big enough to put your phone and your keys in which is just what I need but that's really all you can store there. The colors are so pretty with the lime green nylon material inside complementing the gray fabric outside. The best thing is it makes it easy for you to wash it, too! I would have given this 5 stars if it weren't for the button magnetic clasps that close the outside of the bag which always come off when you put the bag down. I'm not sure if this is a case to case basis and I just happen to get mine in this manner but definitely quite a hassle to always clasp them back together every time I have to reach for my bag. The good thing about it is it does not come off when carried on your shoulder (otherwise that would have given me reason to return it). Overall, I love this bag. Works well!

I have had this mat bag for almost a year and I need to get rid of it and get a different kind. The snaps on this bag do not hold at all. Were it not for the velcro straps inside, my mat would be falling all the time. A friend has the same bag and her snaps do not hold either. I would not recommend this bag.
