I've had my bag for 3 or 4 years now. It truly is a real-life Mary Poppins bag! I take it to work, it travels with me as a carry-on, and I also use it as my overnight bag if I travel somewhere for a weekend. Laptop, books, tests, games & lunch? Sure. Books, headphones, medicine (in the lunch pocket), anything that didn't fit in the checked luggage? That's the bag for it. A weekend away with friends? You can pack snacks for everyone, 2 changes of clothes AND 2 bottles of wine ;)
I love it SO much!
