Experience leather's natural beauty through vegetable tanning
This bag's greatest appeal is its natural vegetable-tanned cowhide.
Vegetable tanning is a traditional leather-making method that uses plant-derived tannins to turn raw hide into leather.
Preserving the leather's natural fibers and character, it is prized by leather enthusiasts as a material that develops more charm with use.
While crazy horse leather offers a rugged vintage look through distinctive scuffs and tonal variations, vegetable-tanned leather lets you enjoy a natural sheen, deepening color, and a texture that becomes more familiar to the touch.
When new, it has a pleasant firmness and a smooth, supple feel.
With use, frequently touched areas develop a gentle sheen, and the leather gradually softens and settles in throughout.
The handle you grasp each morning. The shoulder straps you touch whenever you put it on. The flap that moves as you pack and unpack.
These ordinary daily gestures gradually help the leather mature.
An ideal material for those seeking a long-lasting bag whose changing leather character they can enjoy.
Classic double straps and a soft leather silhouette
A generous flap and two vertically positioned leather straps.
The nostalgic design recalls traditional outdoor bags and classic leather rucksacks.
A dimensional front storage pocket adds depth to the bag's overall appearance.
Understated metal hardware accents the beautiful brown leather, naturally balancing elegance with rugged character.
The soft cowhide body also adapts naturally to the amount you carry.
Pair it with a jacket or shirt for understated business casual. Combine it with denim or workwear for a characterful vintage look.
A timeless design you will want to keep using for years.
Fits 15-inch laptops. Carry work essentials and everyday items together
The body measures approximately 30cm × 17cm × 41cm.
The deep main compartment holds everyday essentials such as a laptop, A4 documents, planner, wallet, and gadgets.
Inside, a laptop compartment is complemented by a smartphone pocket and a zippered pocket.
This layout makes it easy to organize small items by use, whether for work or school.
With approximately 17cm of depth, it also accommodates bulkier items such as a charger, small pouch, water bottle, or lightweight jacket.
It offers greater flexibility for varying loads than a typical slim business backpack.
Drawstring opening and magnetic flap
The opening features a classic drawstring construction.
Pull the cord to cinch the opening, adjusting it easily to the amount you carry.
The large flap also features magnetic fasteners.
It retains the look of classic buckles while taking everyday opening and closing into account.
A construction designed for real-world use as well as visual appeal.
Convenient side pockets and top handle
Pockets on both sides of the bag can hold a bottle, folding umbrella, and similar items.
Frequently used items are accessible without opening the main compartment, making them useful for commuting and travel.
An easy-to-grasp leather handle is positioned at the top.
It makes the bag easy to handle when taking it out of a car or moving it indoors.
The curved shoulder straps follow the shoulder line. Adjustable lengths let you adapt the carrying position to your build and clothing.
From workdays to days off. A natural fit for an adult lifestyle
For business and commuting
Carry your laptop, A4 documents, planner, charger, and more together to the office.
The natural sheen of genuine leather and the classic design pair well with jackets and business-casual clothing.
Enjoy an understated presence that sets it apart from an ordinary nylon backpack.
For leisurely city walks
Pair it with your everyday denim, shirts, or knitwear for visits to cafés and bookstores.
With room for a wallet, smartphone, camera, and small pouch, it is ideal for a relaxed day exploring the city.
The soft leather texture complements an effortless, mature casual style.
For travel and weekend outings
Pack a change of clothes, tablet, toiletries, and more for a short weekend trip.
With the substantial character unique to genuine leather, this backpack still leaves both hands free for convenient travel.
It serves as a refined travel bag that looks at home in hotels and cafés along the way.
For student life and hobbies
Also recommended for students carrying laptops, study materials, and writing supplies.
It can also hold hobby equipment such as a sketchbook or photography accessories.
Its versatility in everyday life gives you more opportunities to enjoy the leather's aging process.
Approximately 1.9kg. The substance and presence of genuine leather
The weight is approximately 1.9kg.
Unlike lightweight nylon backpacks, it has the substantial weight you would expect from a genuine cowhide bag.
It suits those who value the texture, presence, and pleasure of using natural leather over lightness alone.
Adding a laptop or documents increases the total weight, so adjust your load when carrying it for extended periods.
Individual variations in natural cowhide
Top-layer cowhide may show natural wrinkles, minor scratches, vein marks, uneven coloring, and differences in grain.
Small marks acquired as the animal grows and variations between different areas of the hide are characteristic of natural leather.
Vegetable-tanned leather also changes in color and sheen over time through exposure to sunlight, friction, and oils from your hands.
Even the same model gradually develops a different character depending on its owner.
Enjoy the individuality that only a natural material can offer.
Color transfer and care
Dyes, moisture, and friction can cause natural cowhide to transfer color onto light-colored clothing.
Especially when new or in rainy weather, avoid strong friction against white, beige, or other light-colored garments.
Moisture can also cause stains or color changes in vegetable-tanned leather.
For routine care, wipe gently with a soft, dry cloth.
If wet, remove moisture promptly and let it dry naturally in a well-ventilated, shaded place.
If the leather becomes dry, you may apply a small amount of a care product suitable for vegetable-tanned leather.
*Care products may darken the leather. Always test on an inconspicuous area before use.

Leather Colour Transfer and Care
Leather dyes and finishes can transfer onto clothing, furniture or other fabrics. Friction, moisture and perspiration can increase the risk. This can happen with new leather and does not always disappear after a fixed period of use.
Why colour transfer happens
Leather is a natural material, and finishes vary. Contact with damp fabric or repeated rubbing can move colour from the leather surface onto another material. Take particular care with light-coloured clothing, bag linings and furniture.
Taking care during use
Before first use, wipe the surface gently with a soft, dry cloth. Avoid prolonged contact with light-coloured fabrics, especially in wet or humid conditions. If the leather gets wet, blot moisture away and let it dry in the shade with airflow, away from heaters and direct sunlight.
Cleaning and storage
Choose care products suitable for the specific leather finish. Follow their instructions and test on an inconspicuous area first, since cleaners, oils, creams and sprays can change the colour or texture. Do not assume a care product will make the leather waterproof or prevent all colour transfer.
Store leather items in a dry, ventilated place away from direct sunlight, heat and humidity. Keep differently coloured leather and light fabrics from rubbing together during storage.
