The Upcoming Briefcase

Our upcoming briefcase is built for a decade of journeys. Pre-orders open soon.

We’re currently in the testing phase of the next Kasperi model — a briefcase refined over years of experience in designing premium leather shoulder bags. Pre-orders will open within a month, with deliveries expected by the end of 2025 and into early 2026. Details are still subject.

This is your opportunity to join from the very beginning — and secure a piece that’s designed to last a lifetime.

Whether you move through the city by bike, train, or plane, this leather briefcase keeps your essentials close and protected — with everything in its place. It’s built to stand up to daily use and travel, while looking better with every year of wear. Handcrafted at our own Workshop in Hämeenlinna and made from full-grain vegetable-tanned leather from SOHRE tannery, this is a piece to grow old with.

Drawing from the DNA of our best-selling shoulder bag — originally developed for transiting on bike in the city. This is the next step in our evolution. We’ve kept the rider-friendly features like the stabilizer strap and added the carry-on handle, and structured form to meet the demands of daily commuting, serious travel, and modern work life. It's the true overlander of briefcases — one that fits your tools, adapts to your style, and travels with quiet confidence.
