I have the classic Kanken but I wanted something smaller to take the place of a purse. Because me and purses aren't friends. Plus I use this to carry a few art stuffs whenever I feel taking my sketchbook places. Even though its pretty small I can put a bunch of stuffs in it, it actually fits more things than I thought it would. On the inside I can fit my 5x8 sketchbook, a bunch of colored pencils, a magazine, pencil case, sharpener, wallet, and even my giant 32oz Nalgene water bottle! With a little more room to spare. In the inside back pocket I can fit my 10" tablet. The outside front pocket is kinda hard to get into so I put things I don't need much in there like a small hand lotion, chapstick, small perfume, some stray makeup lol. Then the side pockets are pretty small but my sunglasses fit perfectly on one side and my phone in the other. Compared to my classic I can't help but say awww to the mini because its so adorable and small! Overall I'm glad decided to get it, its too perfecttt!Also to the people saying the fabric feels too stiff that is how a Kanken is supposed to be. Eventually the fabric will soften with use and age, and the zippers will get easier to open. You have to break it in like shoes! :D
