Great mini backpack
Color: Black
I love this backpack purse! It has so many pockets; 2 side pockets great for water bottles, umbrella, or my sunglass case. And I love the safety features. The only reason I gave it 4 stars instead of 5 is that the adjustable straps sometimes slip out. I will need to bring it to the shoe repair shop to have one more fold sewn into the end of the strap to prevent it from continuing to slip out.

Handy backpack!

Love it! Perfect for a plane ride and trips to amusement parks or hikes! Both side pockets will hold a water bottle! Just what I was looking for! The color is pretty too! Much prettier in person!

Great Bag
Color: Brown
Okay I was hesitant on buying this bag. Finally did it. I can say OMG this bag is everything. I have recently started to love carrying the backpack bags as everyday bags. The one I have is a little big so looking for a smaller one. This one is more medium size with plenty of pockets. The color was beautiful. It seems it will hold up for a while.
