No.540 Attach Case | LE Bison Black

The No.540 is a completely unique, exclusive and retro inspired design inspired from the classic 80’s style attaché hard cases. Introduced in 2026, the No.540 delivers the functionality of an executive attache with modern styling and a full 3/4 zip body in a semi-hard case. THE DESIGN | An Organized Semi-Hard Case Our most structured men's semi-hard briefcase built with a structured body and a top carry handle reinforced with a steel bar for structure and weight support. The interior is fully lined with premium fabric and leather utility panels and pockets for the ultimate in organization. The top handle is comfortable in the hand and the steel bar supports more weight than is needed. We use a 32” #10 Ykk USA 2-way brass zipper that extends almost completely around the face, making access to the interior easier than the typical top-zip briefcases. The back panel has a 11” brass zipper pocket that is lined with genuine suede and a rear trolly strap to attach to rolling luggage.  THE LEATHER |  Trimmed "Shrunken Grain" Bison Shoulders The No.540 is made from the trimmed shoulder and neck section of the bison hide. We hand-trim each bison hide, removing the shoulder/neck section with the most pronounced and largest grain patterns. The larger mid and lower sections are used most products to maintain better grain consistency. The face and back panels of the No.540 will be cut from the shoulder/neck of the hide, showcasing the rugged and bold American bison texture. The trim panels, ring loops and trolley strap are made from Horween® 8oz. latigo.  JAPANESE Cotton Lining We lined this black No.540 with a premium 10oz. 100% cotton herringbone fabric from Yoshiwa Mill in Japan. The fabric is typically used for lightweight jackets and apparel and makes an amazing bag liner.
