I got the smaller version. It is perfect for carrying the essentials. I have been using it all summer for shopping, travel, errands, etc. One of the straps is starting to separate from the bag, but I like this little backpack enough that I will take it somewhere to get it fixed.Love my bag! I use it every day!I have used this bag several times. It is so convenient to be able to open into a backpack once it gets heavier. I like the sling bag style but having both styles in one is so convenient!I was going to return it, because it was so small. But I ended up keeping it. I do like it . I keep it in the car ? and instead of carrying my big purse ….. if running for a quick errand I just use the bookbag. We went to a museum and it ended up working great. I was able to bring in just what I need carry it on my back and off we went. It fit my phone ? battery charger and earbuds ….. keys ? and some cash ?.I absolutely love this item it's so light weight and just the right size I can fit everything I need in it and the size is just rightMy daughter strap brokeI like the fact I can use my portable cell phone charger with tis item. It will be very helpful when I'm out and about.This bag is just small enough Sleek enough and what I expectedI bought this thinking I could use this to carry my personal items including my iPad. The description states that a 9.7” iPad will fit in the bag and the pictures provide appear as though it would fit. This is not the case, I was not able to fit my iPad in the main compartment which is very disappointing. The quality of the bag is good but It is definitely smaller than advertised.I was contacted by the seller whom advised me that they have a medium size version of this item. They went above and beyond to assist me in rectifying the situation and I is it got the medium size version which does accommodate my iPad. I appreciate how the seller values the customer.I love this bag!! It’s the perfect size. I’m able to fit my big wallet, a book, two puffer (discs), epi pen, phone and a small glasses case in the zip compartment what room to spare. The extra pockets has room for more stuff. I’m able to put what I need in there WITHOUT the bag being bulky. Most days I leave the strap zipped and just throw it over my shoulder. Other days when I’m exploring, or have my hands full i unzip the strap and it becomes a mini backpack.I originally bought the smaller version of this bag thinking it could fit a standard size iPad as I wanted to use the bag for my day to day and travel. However the smaller version did not fit an iPad. I advised the seller whom shortly after reached out to me advising that they had this version which is a medium size and would accommodate my iPad. The seller did everything they could to ensure I was happy with the product which I appreciated as a customer. The bag is a good size but not too large and can easily hold your day to day items such as iPads, wallet, phone small books etc. The quality also seems very good and seems like it will last.great little bag. I use it when I’m driving, riding my bike and just generally, for example, when doing the grocery shopping. Carry my phone, wallet, keys and a couple of other small items. Can hold two small drinks - cans, water bottle. I wear around my torso where it is easiest to access and doesn’t get in the way.I really like this lightweight knapsack. Great for my daily walks. However, it is advertised that the side pockets will hold a water bottle or umbrella and its even pictured this way. In fact the side pockets are too small to hold a water bottle or umbrella. The mesh is too tight and is too gathered at the bottom to provide enough of a base. The side pockets are useless so have to put my water bottle inside and it fills the compartment. This knapsack is good for a short walk but wouldnt work for a day trip.
