I bought the purple rose print which is beautiful--I have gotten several compliments on it. I bought this bag for my trip to my oldest son's wedding in Barcelona, Spain. I use a CPAP machine and I need a bag sturdy enough to hold the many parts of the machine, surrounded by bubble wrap. The "fabric" is not mere canvas--it is a sturdy nylon which is doubled over for about 3@ at the top, making the top of the bag very secure. It closes with a long zipper at the top, but because the zipper is longer than the bag, I know that some people have commented on the lack of security, since if you were not watching someone (if they understood where the openings were, could reach in at either end and steal something. Now to that I say that I always keep HOLD of my bag unless I give it to my husband to hold for me if I need to use the restroom. And I actually LIKE the way the zipper is extra long, because it makes it much easier for me to open the bag. Inside the bag thee anre NINE pockets of various sizes--you can easily separate things like your different boarding passes and snacks. At either end on the outside of the bag there is a webbed pocket which could be used to carry something that got wet and wrung out but you want to keep it separate from stuff in the interior. Some people complained that these pockets were not helpful for carrying bottles of water and I think they are right--the pockets are much too wide and too short. But they would be helpful to put a baseball cap in--or some other kind of small hat. There are TWELVE unzippered pockets on the OUTSIDE of the bag--I used one for a small pkg of facial tissues. Because they are not zippered they would not be sure for credit cards and such--neither is the inside. But I put my passport and credit cards in a bag that crossed over my chest so that it hung in front of me and not in back or on my side. I had heard that the Barcelona airport was notorious for pick pockets!!!! These handles on either side of the bag are VERY sturdy. It comes with a shoulder strap but I did not use it--for the sake of security in Barcelona and for the life of me I could not get the shoulder strap open enough to connect to the bag. Finally, the bag comes with a small matching bag that is the size of a makeup bag--it has a loop handle and zips closed at the top. The fabric of the bag and makeup bag nylon and therefore waterproof.My husband and I got stuck overnight once after an unseasonably massive snowstorm near Denver, CO at Thanksgiving. So ever since then I have packed some extra necessities in this bag--makeup bag, comb, extra socks and underwear, light day pads, small deodorant, facial cleanser, etc. There was PLENTY of room for all of this ,my CPAP machine (which has a long electrical cord, a "brick," a long tube, a nose cushion and the large CPAP machine itself. All this stuff fit nicely in this bag, as well as a book.Because the sides of the bag are not stiff it fit perfectly under the seat ahead of me, along with my purse. Easy peasy. So overall I think this is a GREAT value for the money. Other than facial tissues I am not sure what I will put in the outside pockets, other than perhaps a deck of cards or several paperback books--you could probably fit two in some the outside pockets--as well as some trail bars and other snacks. I am working on not snacking. But obviously the more you put unit the heavier it becomes, so that is a consideration, if like me you are not that strong.I think this could be a GREAT bag for a teacher. I plan to use mine for many years to come.
