Very nice
Color: Green
It’s such a cute backpack! I’d get the beige color if using for work. The olive green can look a bit flashy in a corporate environment :( old people don’t know how to have fun

Great Backpack
Color: Green
I love this backpack which can carry laptop for work. Before I always carried two bags when I went to work. Now, I only need to carry this backpack which is enough for me everyday. The color is great too. Even though I carried a lot of stuff, I did not feel that heavy at all.
