Leather Backpacks — Full-Grain Crazy Horse, Built to Age Well
Every leather backpack in this collection is cut from the same hide: full-grain crazy horse cowhide, 2 to 3mm thick, oil-tanned so the surface shifts color when you bend it. No coating, no corrected grain, no shortcuts. The brass hardware is solid — not plated — and the seams are double-stitched with waxed thread. These are the details that separate a bag you'll keep for a decade from one that falls apart in eighteen months.
Eiken designs every model in-house and sources the leather from the same tannery we've used since day one. Every backpack ships with a two-year warranty against manufacturing defects, because we know exactly how they're made.

The Crazy Horse Leather — What It Is, Why It Matters
Crazy horse leather is full-grain cowhide treated with a hot wax finish that penetrates the fiber. The result is a surface that reacts to touch — run your thumb across it and the color shifts lighter where pressure is applied. Over months of use, the leather develops a patina that's entirely yours: darker where your back rests against it, lighter at the edges, creased where you grab it every morning. Two people can buy the same ARYN and end up with bags that look nothing alike after a year. That's the point.
It's also practical. The wax treatment gives the leather natural water resistance — not waterproof, but enough to handle a rain shower without panic. Scratches buff out with your finger. And because the grain hasn't been sanded or corrected, the leather is structurally stronger than most alternatives at this price point.
For Work and Laptop Carry
The ARYN, HORE, ROYA and ROSKA all have a padded laptop sleeve that fits up to 15 inches. They share a structured silhouette that looks right in a professional setting without looking stiff. The LYVE and VINSON push further into business territory — cleaner lines, more compartments, designed for people who carry a laptop plus documents plus chargers every day.

For Travel
The WATERLOO (25L) and URSUS (19L) are the two largest packs in the collection. The WATERLOO fits a 15" laptop alongside a weekend's worth of clothes — at 48 cm tall, it's the biggest backpack Eiken makes. It has a top-loading design with a buckle flap. The URSUS uses a roll-access opening that gives you better visibility into the main compartment. If you're looking for a leather backpack that doubles as a carry-on for short trips, these are the two to compare.
For Women
The AYA (20L, 1.5 kg) and UMEA (15L, 1.5 kg) are scaled-down models — shorter back panel, narrower straps, and a cleaner profile that works with more outfits. Both fit a 14" laptop. The AYA is zip-access with a simple exterior; the UMEA has a more structured look with a front flap pocket. Neither is exclusively a "women's" bag — they work for anyone who prefers compact carry.

Leather Backpack Care — The Short Version
Crazy horse leather is low-maintenance by nature, but a few habits will keep it in shape. Wipe dust with a dry cloth. If it gets wet, let it air dry — never use a heat source. Apply a leather conditioner every three to four months, or whenever the surface feels dry. Scratches usually disappear when you rub the area with your finger. Store it stuffed with paper to keep its shape. That's it.
Frequently Asked Questions
Can leather backpacks get wet?
Crazy horse leather handles rain well thanks to its wax treatment. Wipe excess water with a cloth and let it air dry — avoid hair dryers or radiators. For prolonged exposure, a waterproofing spray designed for leather adds an extra layer of protection.
Are leather backpacks suitable for daily use?
That's what they're designed for. The padded straps distribute weight evenly, most models include a dedicated laptop sleeve, and the leather itself gets more comfortable with use — it breaks in, not down.
How long will a crazy horse leather backpack last?
With basic care, well over a decade. Full-grain leather is the most durable grade available. The brass hardware won't corrode, and the waxed stitching holds up to daily stress. These bags age — they don't deteriorate.
Leather backpack vs canvas backpack — which is better?
Different tools for different needs. Leather is heavier but more durable, develops a patina, and looks sharper in professional settings. Canvas is lighter, more casual, and easier to wash. We make both — our canvas backpacks use waxed cotton with the same brass hardware. If you split time between office and trail, leather for weekdays and canvas for weekends is a solid system.
How do I break in a leather backpack?
Just use it. Crazy horse leather softens naturally with daily wear — the wax finish redistributes as the bag flexes, and the cowhide molds to your back over the first few weeks. No oils or tricks needed. If the straps feel stiff initially, bend them back and forth by hand a few times.
What warranty do you offer?
Every backpack comes with a two-year warranty against manufacturing defects. If something goes wrong, email info@eikenshop.com with photos and we'll sort it out.
What is the return policy?
14-day returns on unused items. Full details on our Return & Refund Policy page.
