Need a minimalist bag/satchel recommendation

Hey everyone I've taken a new role at work and that required frequent overnight travel. I've purchased a fantastic overnight bag that holds all my necessities (clothes, dopp kit, laptop etc…) that are required for my short stay. That's great because I only have one bag to lug to the airport, but tt leaves me without a bag to carry to the client's office. So that puts me in the market for a minimalist (aka small), preferably leather, laptop bag that I can fit inside the overnight bag. The only requirements are that it can hold a 15" MacBook, power cord, notebook and maybe a few cables.


Any suggestions? Currently I'm looking at either having something custom made or this: Zip Brief MacBook Case

Highly recommend Brenthaven products. I've never used any of their minimalist offerings, but the quality is second to none.
