My first RM bag was from a sample sale and I got the brown/chocolate MAB. I carried that bag the first couple of weeks and had thought to myself that I wish the bag were a tad smaller since I don't need it to carry clothes around, just work stuff and everyday items. Well fast forward to a couple of months later and joining TPF and I find out there is a smaller version called the morning after mini. I had to get one to compare and I am very satisfied with both styles. Someone had posted that the MAM was similar to a LV speedy 30 which I'm familiar with and its true only difference you can wear the mam on your shoulder and it has pockets both inside and outside the bag. I still keep both bags in rotation but would prefer the MAM over the MAB for everyday use.
