Full-grain versus split leather

Most leather wallets are made from split leather — the lower layer of the hide, pressed and coated to resemble quality leather. Full-grain leather is the top layer, including the original grain. It is stronger, more abrasion-resistant, and the patina that forms is a property of the material itself, not a coating. Saddleback uses only full-grain calfskin, vegetable-tanned in Mexico.
Vegetable tanning versus chrome tanning
Most modern leather goods are chrome-tanned — a chemical process that is fast and produces a soft, uniform product. Vegetable tanning takes weeks and uses plant tannins. The result is a stiffer leather that breaks in more slowly but is denser and stronger over the long term. Vegetable-tanned leather develops a deeper patina and looks better as it ages.
The Slim Wallet in practice
The Saddleback Slim Wallet has three card slots and a note pocket. It is deliberately minimal — no zip, no extra pockets for receipts. New, it is stiff; after three months of daily use, it has moulded to your pocket and the cards you carry. It thickens slightly as the leather breaks in, but remains thinner than most multi-card holders.
The guarantee
The 100-year guarantee is not symbolic. Saddleback will repair or replace any product that fails due to a defect in materials or workmanship. The fact that almost no one ever needs to claim it is the real evidence of the quality. The tongue-in-cheek tagline — "They'll fight over it when you're dead" — is a literal promise: this thing will outlast you.
