Simple minimalist lines, heavy gauged string, copper rivets, solid buckles and our rugged 10 oz. hide makes our newest satchel. My goal with this new No. 4313 was to create the strongest satchel on the market with as little excess as possible. This feels more like a standard-sized briefcase ideal for a 15" MacBook Pro with a sheath and a few inches of files, books or magazines. Adjustable strap, optional monogramming and inserts. Approximate size 16" x 10" x 3.5". Handmade in the USA and guaranteed for life. Check out the video of our No. 4313 satchels in both standard and large sizes with additional options.
