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!

Color: Green

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!

Very nice product, more room, can organize very well, hopefully will last long. Previous purchases of small backpack for women did not last long .
