This is NOT a full sized backpack. If you are not familiar with the Kipling Seoul line they have a small (this bag...slightly bigger than a purse backpack), a regular (or large) & an XL. But Kipling bags are amazingly durable & mine last forever. The only thing is that I bought Galaxy Blue & it is pretty much purple. I like the style, I just wish it was blue instead of purple. I love the small Seoul for day trips.Perfect size bagGreat kipling seoul small backpack that easily doubles as a purse. The correct measurements are 10"L x 13.75"H 4.5"D. Vibrant red color is exactly what I wanted.The newest model does not include a key clasp. I was so happy that my bag does! Yay for no lost keys! A 16 oz water bottle fits in the size pockets too. The padded straps are worth the price point.. Very happy with the purchase. I hijacked my husband's account to write this review.Really small and looks like a baby backpack. Too expensive for the size.Not sure how water resistant this bag is but it's great for travel. And it looks super cute in pictures, too! I bought this for my very short mother and it fits her build and her small shoulders.
