We took this backpack on our honeymoon and it was perfect as a carry-on for my husband and we used it the whole week while we were bike riding

In fact, I liked the 20ml version so much after I received it I went back and bought this 30ml version! You could easily fit magazines and other sizable things into the 20ml, for most cases that's the best balance of capacity and foldability

Love it a lot I really like this backpack

I have nothing bad to say about this bag

I was really worried that the fabric would be too thin, so I decided to test it out with a trip to Universal Studios

Oh, and the shoulder straps are padded nicely which was unexpected, but it works
