Approximately 20 cm wide, 15 cm high and 5 cm deep.
It sits close to the body without projecting too far, creating a light, easy look whether worn on the shoulder or across the body.
It has more room than a phone-only pouch while remaining more compact than a conventional shoulder bag.
It is just the right size for anyone who wants to carry only everyday essentials neatly.
The rich character unique to crazy horse leather
The leather itself is one of this bag's main attractions.
Crazy horse leather is genuine leather that lets you enjoy natural variations in shade and scuffing rather than an overly uniform surface.
It starts with a slightly matte texture. Areas touched by your hands gradually develop a sheen, and the colour becomes deeper.
Small scuffs and creases blend into the surrounding texture as you continue using it.
Rather than keeping the bag exactly as it looked when new, everyday use helps it become your own.
Enjoying this change is part of the appeal of choosing crazy horse leather.
Keep your phone and wallet together neatly
Examples of everyday items you might carry include:
- Smartphone
- Small wallet
- Card holder
- Key case
- Wireless earphones
- Power bank
- Lip balm
- Everyday medication
- Small gadgets
Choosing only what you need naturally helps keep the bag organised.
Instead of putting everything into a large bag, select just what you need for that day.
It is an ideal match for that lighter way of going out.
A front pocket for quick access to frequently used items
A generously sized slip pocket is positioned on the front.
It is useful for items you reach for often, such as a phone, transit card or tickets.
There is no need to open the main compartment every time, making small everyday actions smoother while travelling by train or shopping.
A zip closure to keep important belongings contained
The main compartment closes with a zip.
It keeps important belongings such as your wallet and cards securely inside.
The wide opening at the top makes it easy to see the contents and put things in or take them out.
An interior slip pocket lets you organise small items separately from the main compartment.
An adjustable shoulder strap
The shoulder strap can be adjusted in length.
Shorten it for a close fit against the body, or lengthen it for a more relaxed crossbody style.
Adjust the position to suit your build, clothing and preference.
The strap also carries the character of leather; together with the understated hardware, it enhances the vintage feel of the whole bag.
For commuting and short outings during the working day
It is convenient for lunch or nearby errands when you do not need a large work bag.
Transfer just your phone, wallet, card holder and keys, and head out lightly.
The understated texture of genuine leather keeps it from looking too casual and pairs naturally with a jacket or smarter clothing.
For weekend walks around town
Shopping, cafés, a walk or a meal with friends.
Put in only what you need and head out easily with the bag worn across your body.
The texture of genuine leather adds an accent even to a simple outfit of a T-shirt, shirt or denim.
A secondary bag when travelling
A separate bag for exploring town is useful alongside your main luggage.
Keep frequently used items such as your phone, wallet, hotel key card and passport together.
Its compact size also suits storing it inside a suitcase or larger bag while in transit, then taking it out at your destination.
The individual character of natural cowhide
Crazy horse leather may show:
- Natural creases
- Small scratches
- Uneven colouring
- Variations in grain
- Scuff marks
- Texture differences between parts of the hide
These are characteristics of natural leather rather than quality defects.
Cowhide varies according to the part used, so even bags of the same model will not have an identical leather appearance.
Please enjoy these differences as part of each item's individuality.
About colour transfer
Dyes, oils, moisture and friction can cause crazy horse leather to transfer colour.
Be especially careful about strong rubbing against white, beige or other light-coloured clothing when the bag is new or in wet weather.
The finish gradually settles as the leather is used and broken in.
Care instructions
For everyday care, a light wipe with a soft, dry cloth is sufficient.
If the leather gets wet, remove the moisture as soon as possible and let it dry naturally in a well-ventilated place away from direct sunlight.
If dryness becomes a concern, you can use a small amount of leather cream or oil suitable for crazy horse leather.
Care products may darken the colour. Always test on an inconspicuous area before use.

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.
