I am lucky to have gotten an internship offer to work at an MBB firm for this upcoming summer. I was wondering what kind of backpack I should get that is best for consulting? I want to use the same backpack for everything, including travel and daily work in the office. I want to make sure it is professional. I am willing to splurge as long as it lasts me for my life or as long as possible.

I saw briggs and riley, but are there any other suggestions?
