Martin Thin Leather briefcase big on space

Started 2023 traveling with my new Martin Thin Leather briefcase and man its big on space. Holds everything I need while also looking great. Super pleased with this purchase.

Todd Ague
Fantastic quality, fit/finish and durability

Just broke my Martin briefcase in on a recent cross-country flight and it was all I had hoped for:
1) Rugged and able to withstand being shoved under the seat in front of me and used as a footrest without getting scuffed;
2) Able to hold my laptop, power cables, earphones, notebook, pen, passport, work badge and wallet safely and without anything going missing;
3) Comfortable, professional appearance, and easy to “wear” using the shoulder strap while navigating air terminal corridors and dragging a roller bag behind me.

This briefcase is sized right, well-made and will serve me for decades to come. Highly recommended.

Another fantastic product!

My Martin briefcase just arrived in flawless condition. Like my Go Forth Goods duffle, this will last forever. I bought it knowing it will be kicked around in transit and stepped on under the seat in front of me on airplanes.

Durability, size, build and leather quality are all top notch. I highly recommend this Made in USA item!

Martin Thin Leather Briefcase

This is a perfect size for light office carry. I go back and forth between this and the Harris Briefcase. A perfect combo! Highly recommend. It carries really well.
