I use the big one everyday for work and can carry everything I need! iPad with a thick case, water bottle, large wallet, snacks, portable charger and 4 different cords, phone, etc. The medium one is perfect for going out. I can hold two packs of smokes, a portable charger, large wallet, and phone, and a cord no problem. The style and quality is great too!

The description was spot on. Love the yellow color.
