Guys... it's okay to have a man bag
It is actually encouraged if you partake in business settings. And it can make you look (and feel) important. I copped one for myself after getting my MBA, but that was more as a symbolic gesture than a requirement. Whatever the case is for you, go forth and own it with confidence. Almost everyone has a laptop these days, so why not carry it in style? Even if you don't use it for a laptop, it's great for day trips or a lightweight carry-on for those who like to travel like a ninja. A ninja with a man bag. Carry on, gentlemen.
You don't need to drop stacks on a man bag to be stylish, but you will get what you pay for so try to invest in quality.

Alternatively, you can search places like Etsy for leather messenger bags. I've gotten 4+ years of use on mine, and it's been all over the world. I've used it as a carry-on during several trips. It fits my laptop, iPad, headphones, any wires/plugs, toiletries and even some emergency spare clothes if needed.
