Let me first state that I love all the MM towels I have.
I've sampled numerous brands and haven't found a higher quality towel anywhere. I have Crazy Pile, Cloudbuster, Waverider, DMC standard and XL.
All the towels will easily fit back into the bags except the DMC. I currently use the XL bag for my standard size DMC. It's just the right size.
Just a suggestion, if the bags were bigger for the DMC towels, it would make it easier to re-use them without having to "stuff" them in. The zip can easily pop off when trying to close as well.
