This perfectly designed backpack is ruined by horribly design straps. The backpack itself is the best I found and I love it so much I’ve tried to find someone that will so new straps onto it for me. The straps it ships with are an odd c shape that push all the weight of the backpack to the outside of your shoulder. If you try to carry it with one strap, it immediately falls off the outside of your shoulder. When you carry it with two straps it tries to fall off of both shoulders. I’ve owned five or six business backpacks and have never experienced such uncomfortable, un-functional, and aggregating straps as these. As much as I love the functionality of the bag, I have to suggest you run the other direction based on the design of the straps.
