Our highest-capacity briefcase, the 24-Hour Briefcase combines the organizing ability of our Padded Computer Bag with the sleek design of our Original Briefcase. The waxed Tin Cloth material protects gear from foul weather and spray. This tightly woven canvas duck has been thoroughly saturated with wax for water resistance. The Bridle Leather handles are vegetable-tanned with tallows and wax added in the final stages, giving the leather a deep luster and lasting flexibility. The main zipper is solid brass from YKK® for a lifetime of rust-free operation. The interior is fully lined with unwaxed cotton, with a padded sleeve for laptops up to 15‚Äù. Exterior zippered pockets have organization pockets inside. Rear trolley strap slides over luggage handles. Detachable, adjustable webbing shoulder strap.
