the fabric was water resistant and none of my belongings got wet under light rain. it fit my laptop, chargers, notebooks, two toiletry bags, plus a puffer vest and a wool tucker jacket. it got me through international customs and TSA quickly. when asked to search my bag for liquids prior to boarding an international flight from south america to the US, the agent complimented my bag, and i made record time through the line and to my seat on the plane. the zippers work great and have yet to fail me. lightweight and surprisingly sturdy. do be advised that the lighter colors will take on some damage after a few dozen bus rides, but it’s to be expected and i’m not mad at it. great purchase for the price !

Understated, yet very app

Color: Apricot, Size: 16 Inch

I find this backpack to be sleek and modern,. I do not like to carry bags that take attention away from me and onto my things. It is sleek and femine - I love the backpack and I’m glad I bought it…
