Consider what goes inside and what you carry outside. Choose by imagining actual use, not only the visual features.
Choose documents for a short meeting
Today’s discussion is decided, so you narrow down what to carry. A morning spent reviewing the documents and devices needed and arranging your thoughts.
Gather them in a slim bag and head to the person you will meet. A shape for those who prefer selecting the day’s essentials to carrying a lot.
An afternoon out with something to read
On a day without work plans, spend time with the magazine or reading material you have been curious about. Look slowly at articles and photos you might normally miss.
Bring a work bag into your days off too. Enjoy a favourite shape with your clothes and plans, without limiting it to one purpose.
Cowhide shades and detailed interior storage
Made with full-grain Crazy Horse cowhide, it has laptop, zipped, slot and phone pockets inside. The lining is polyester.
After noticing the metal outline, look closely at the leather’s expression. Use this combination of materials with regular care.
For these everyday preferences

Enjoy form in the gestures of use too.
Take W on days when you choose exactly what to bring. Grow familiar with both the outline in your hand and the leather’s shades as you carry it.
Leather character and care
Natural leather varies between pieces, including differences in texture by area, small scratches, wrinkles, uneven color and vein marks. Lighting and screens may make the actual color appear different.
Friction and moisture may transfer color onto light-colored clothes and fabrics. Check that leather sprays, oils and creams suit the material, and test on an inconspicuous area first. Care cannot completely prevent color transfer.
After use, store in a well-ventilated place away from direct sunlight, heat and humidity. If the smell after purchase bothers you, air it in the shade in a well-ventilated place. The time needed for the smell to fade varies between items.

What Is Crazy Horse Leather?
Crazy horse leather is cowhide treated with oils and waxes to create a finish that changes in colour and surface character with use. Despite its name, it is not horse leather.
A finish that develops character
Bending or rubbing the surface can bring out lighter and darker areas. Areas that are handled frequently may develop a sheen, while creases and surface marks contribute to a patina over time. The way the finish changes depends on the item, how it is used and how it is cared for.
Natural leather also varies in grain, texture and colour. Product photographs show examples; lighting, screen settings and the individual piece of leather can affect its appearance.
How it differs from other materials
Check the material on each product page. A canvas bag with crazy horse leather details is not an all-leather bag. PU with a crazy horse-style appearance is synthetic leather, and needs different care from genuine cowhide.
Choosing a bag or wallet
Choose the shape, dimensions, weight and storage for what you plan to carry. Do not rely on a laptop’s screen size alone to judge fit; compare the device’s actual measurements and the thickness of any case. For a smaller accessory, check the length and thickness of the tools or items you want to store.
Moisture and colour transfer
The leather is not fully waterproof. Avoid heavy rain and prolonged wet conditions. Friction, perspiration and moisture can cause colour transfer, particularly onto light-coloured clothing and fabrics. A protective spray or conditioner cannot guarantee that colour transfer will stop.
Everyday care
- Wipe dust gently with a soft, dry cloth.
- If wet, blot away moisture and let the leather dry in the shade with good airflow.
- Avoid direct heat, sunlight and humid storage.
- Use care products suitable for the finish, following their instructions and testing on an inconspicuous area first. They may change the colour or texture.
- If a new item has a noticeable leather smell, let it air in a shaded, ventilated place. The time it takes to settle varies.
When to ask for help
Natural variation does not mean every problem is part of the material’s character. If you are concerned about damage, construction or another issue, contact cowmono with your order number and photographs.

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.
If you are concerned about a particular item, contact cowmono with your order number and photographs.
