Frank Clegg Leather Briefcases: The Zip-Top Commuter, Fall River Bench-Craft and Vegetable-Tanned Harness Leather
An in-depth guide to Frank Clegg Leatherworks' Zip-Top briefcase: handcrafted in Fall River, Massachusetts, using custom-tanned harness leather, solid brass Swiss riri hardware and traditional bench construction.

Fall River workshop heritage: fifty years of Massachusetts bench-craft
In an era when historic American leather companies have overwhelmingly outsourced production to high-volume overseas contract factories, Frank Clegg Leatherworks remains a steadfast exception. Founded in 1970 by Frank Clegg in Fall River, Massachusetts—a city steeped in New England's historic textile and industrial manufacturing heritage—the atelier continues to operate as an independent, family-owned bench workshop. Today, Frank works side by side with his sons, Ian and Andrew, preserving hands-on leathercraft traditions that have largely vanished from commercial luggage manufacturing.
The Fall River workshop operates strictly on small-batch bench principles rather than fast-paced assembly lines. Hides are individually selected and hand-inspected for grain density and temper. Key structural panels are hand-cut to align the grain orientation with the bag's load points, edges are skived to precise thicknesses, and each piece is assembled by skilled craftspeople who take pride in executing every step of production under one roof.
Anatomy of the Zip-Top: vegetable-tanned harness leather, riri zippers and hand-burnished edges
The Zip-Top briefcase is Frank Clegg's signature business silhouette, designed for executives, academics and creatives who require understated elegance paired with extreme durability. The foundation of the bag is Frank Clegg's proprietary American vegetable-tanned harness leather. Hot-stuffed at the tannery with natural tallows, oils and waxes, this heavy full-grain hide possesses an extraordinarily dense temper that resists surface gouging and moisture penetration while retaining a supple, waxy hand.
Hardware selection reflects the same uncompromising ethos. While commercial bags routinely cut costs using zinc alloy zippers that jam or corrode over time, Frank Clegg fits heavy-gauge Swiss riri solid brass zippers. Widely acknowledged by master leathercrafters as the world's finest closures, riri zippers feature individually cast, machined and hand-polished teeth. This ensures a frictionless glide that will never snag or scratch laptop casings and wristwatch crystals when reaching into the bag.
Nowhere is the atelier's bench-craft more evident than on the edges. Rather than applying plasticized edge paint that inevitably cracks, peels and separates after a few seasons of flex, Frank Clegg artisans hand-bevel every exposed edge. The perimeter is dyed with water-based stains and hand-burnished using friction wooden slickers and natural beeswax, producing a rounded, sealed edge that ages alongside the hide.

Internal architecture, capacity and daily commuter ergonomics
Proportioned for real-world commuting, the Zip-Top measures 40.6 cm in length, 30.5 cm in height, and 10.2 cm in depth (16" x 12" x 4"). This profile strikes an ideal balance between slim mobility on crowded trains and generous interior volume. The main compartment effortlessly swallows a 15-inch or 16-inch modern laptop, a leather document portfolio, power adapters, and personal tech accessories without unsightly bulging.
Inside, the bag features thoughtful, functional organization executed entirely in premium materials. A full-length internal divider separates work documents from electronic hardware, complemented by a dedicated zippered security pocket for passports and valuables. An integrated leather organizer panel provides tailored slots for fine writing instruments, business cards, smartphone storage, and a solid brass key lanyard.
Carrying comfort is central to the Zip-Top's daily utility. The rolled top handles are constructed around a solid rope cord core, wrapped in thick top-grain leather and secured with heavy-gauge bonded nylon stitching. Unlike flat handles that pinch pressure points or hollow handles that collapse under heavy loads, these rolled grips distribute weight smoothly across the fingers. For hands-free airport or subway navigation, the bag includes a detachable 3.8 cm (1.5") wide bridle leather shoulder strap with a sliding padded rest and custom solid brass swivel snap hooks.
Care, conditioning and patina progression of American harness leather
One of the greatest virtues of Frank Clegg's vegetable-tanned harness leather is its low-maintenance resilience. Because the hide is impregnated with substantial waxes during the tanning process, the leather continuously replenishes itself from within as it flexes. During the first 6 to 12 months of daily ownership, the briefcase requires almost no external conditioning. Routine maintenance should be limited to a weekly brushing with a natural horsehair brush to sweep away dust from welt seams and buffing with a dry microfibre cloth.
Surface scuffs and fingernail marks are an expected part of living with vegetable-tanned leather. Thanks to the high wax content, light surface abrasions can easily be smoothed away simply by rubbing the area briskly with your thumb or a soft flannel rag; the friction warms the oils and draws them across the scuff. If the briefcase is caught in an unexpected rain shower, simply wipe down the exterior with a dry cotton towel and allow it to air-dry naturally at room temperature, strictly avoiding radiators and direct heat sources.
After a full year of commuter use, apply a light coat of neutral, wax-based leather balm—such as Bickmore Bick 4, Saphir Médaille d'Or Renovateur or Frank Clegg's recommended leather cream—once or twice annually. Over time, sunlight, ambient handling and natural wear transform the leather, deepening its colour and bestowing a lustrous, golden-brown patina that cannot be replicated synthetically.
Who the Zip-Top Briefcase is for: practical buyer checklist
