I have a Manduka yoga mat (that I love) and it is a bit too thick and too wide for some of the standard carrying bags. It also doesn't stay rolled up well so is a pain to drag around. I ordered A Manduka Go Play and I am thrilled. The adjustable clip straps are easy to use, stay closed way better then D rings and could fit many different sized mats. It even fits a yogi toes towel wrapped inside my super thick mat. The zipper pocket is perfect for keys, a cell phone, and a small wallet or a few cards. The only thing that doesn't fit is a water bottle. I would highly recommend the Go Play - it makes carrying a heavy large mat way easier and consolidates all the other things I bring into one place.
