I must agree, the Neverfull gets very heavy when you carry it for a longer time, especially with a laptop inside. I had my Neverfull with me when we were in Paris a few years ago, carrying random stuff, wallet, keys, phone etc. not too heavy. But I ended up giving it to my husband after 1-2 hours because I couldn’t wear it any longer. The handles do cut into the shoulders.
I use a backpack for work, because I noticed that my posture gets more and more crooked by wearing heavy shoulder bags. In the end it wasn’t worth the better look of a shoulder bag compared to a backpack
