Waterproof canvas backpack_C
Tax included Shipping fee calculated At checkout
Even if it gets wet or gets rubbed, it still looks good. ── Adults' "tools" become more beautiful as they grow.
An alley after the rain, a dusty garage, a pier with a strong sea breeze, and a morning mist in the mountains. It is in such an environment that the ``true value'' of the material becomes visible. This backpack is a combination of waterproof waxed canvas and natural cowhide straps. It is designed to have a "vintage quality" that deepens the more it is used, rather than the "new beauty" that has been completed from the beginning.
It has a streamlined design that can be used by both men and women, but the focus is on men who like vintage textures. We don't talk with the logo, we talk with the materials and appearance. Great for work, travel, and everyday transportation. Our goal was to create a backpack that will help you look and feel perfect from the moment you put it on your back.
What is waxed canvas? A process that turns “cloth” into armor
Canvas is originally a fabric that is meant to be used up. As the word canvas suggests, it is highly durable and resistant to abrasion. By waxing it, a thin protective film is created on the surface, making it easier to repel water (simple waterproofing). Raindrops form beads and roll, making it difficult to get dirty and easy to clean.
Above all, waxed canvas "brings out taste." Creases, scuffs, wrinkles, and hits. The pattern is the same as how you use it. For those who value the unevenness created by time rather than the uniformity of a new product, there is no material that is more compatible with this one.
Natural cowhide strap ─ “Growing texture” adds dignity to your back
If canvas is responsible for tough practical use, leather is responsible for dignity and luster. The natural cowhide strap becomes softer and more supple the more you use it. Oil on your hands, friction, humidity and dryness in the air—all of these things work together to deepen the color and create a shine.
・First: A tense and calm expression. ・Several weeks: The corners become familiar, and the part you touch becomes slightly glossy. ・Several months: The color tightens, the shadows increase, and the presence of the strap increases. ・Several years: The luster spreads quietly, and the "dignity of ownership" resides on the back.
The aging of canvas and the aging of leather proceed at different speeds. This misalignment creates depth in the expression.
Size and internal design - perfect for both work and daily life
42 x 32 x 12 cm. It's not too big when you carry it on your back, but it can fit everything you need. This is a realistic capacity that is assumed to be used daily by adults.
The internal structure emphasizes the ability to organize as a tool. Equipped with a PC pocket, internal zipper pocket, and cell phone pocket, you can keep items that tend to get lost in your bag in a fixed location.
-
PC pocket: Separately stores laptops and tablets (reduces movement within the bag)
-
Internal zipper pocket: Keep valuables, keys, passport, cash, etc. safe
-
Mobile phone pocket: fixed in a position that is easy to access
``Carry it on your back, then take it down and work.'' This is a structure that allows for a natural line of movement.

User-friendliness that works immediately after purchase ─ Design philosophy that eliminates small stresses
A good bag erases the small stresses of life.
・Rainy days: The waxed canvas easily repels water droplets and the surface is easy to maintain. ・When moving: The soft back structure follows your back and does not interfere with your body movements. ・Organize: Not only do you have pockets, but you can also decide on your role, so you won't have to search for them anymore.
Changing the bag changes the flow line. When the flow line changes, time increases. This backpack is a tool that is strong against such "piling up".
Story by scene ─ The scenery changes every time you carry it on your back
[Biker] Before starting the engine, put your smartphone in a position where you can access it even with gloves on. When you go out on the town, it sticks to your back and doesn't shake easily. The texture of the canvas peeking through the cracks of his helmet while waiting at a traffic light is as reliable as an old garage toolbox. Even when it rains, the waxed canvas remains calm. Along with the smell of wet asphalt, the bag remembers the distance traveled.
[Outdoor] Morning forest. Fog and moisture cling to my skin. This is when simple waterproofing comes in handy. Inside are a notebook, charger, and extra socks. Keep anything you don't want to get wet inside. The toughness of the canvas will give you a sense of security even if you place it on a rocky spot while taking a break. The slight smell of campfire smoke lingers in the wrinkles of the well-worn canvas. That will be the trigger for next weekend.
[Casual] White T-shirt and denim, or coat and boots. Just adding a shade of waxed canvas to the back will complete your outfit. The quality that can be conveyed even without a logo is something that only adults can afford. When I open my PC at a cafe, I can easily take it out of my bag. When placed on a desk, it has just the right balance of ruggedness and elegance.
[Student Life/Reskilling] Lectures, clubs, part-time jobs. My baggage tends to increase and I move quickly. That's why it's so effective to have a bag that's stable to carry on your back and that allows you to easily carry what you need. A laptop in the PC pocket, a wallet and keys in the inner zipper, and a smartphone in the cell phone pocket. If you fix this, you will be able to get ready every morning faster. A few years later, the touch of the canvas and the luster of the leather will become my footprints back then.
[Hobby (Camera/Sketch/Gadgets)] Taking a photo walk around town. Walk with your camera in. Memo and pen, spare battery, lens cloth. When the tools are in place, the feeling doesn't stop. The roughness of the canvas and the luster of the leather create the perfect "blank space" for hobby time. It's not a tool to show off, but a tool to increase your inner satisfaction.
[Travel] What is important when traveling is ease of movement and a sense of security. Open your computer in the hotel lounge. Store your passport and valuables in the inner zipper while you're on the go. Even in sudden rain, the waxed canvas is reassuring. When I got home and put the bag down, there were a few more scratches and wrinkles. This proves that ``the journey has become your own.''
[Others (commuting, companion around town, use as a sub-bag)] The size that can be used every day is actually the most luxurious. It's not too big, so it doesn't hold up too much. Choose only what you need. This habit will make your daily life easier.
How to use it: Turn your backpack into a “life device”
■ 1) Fixed the role of pockets to eliminate “search time”
-
Mobile phone pocket = smartphone only
-
Inner zipper = keys/wallet/passport
-
PC Pocket = for devices only This will reduce the number of things you forget and eliminate the flapping before departure.
■ 2) Always have a PC, charger, and notebook as a “mobile office” set. Work immediately at a cafe, lounge, or on the go. Your bag can become your work base.
■ 3) As a “travel specimen box” For each trip, store small tags, tickets, and scraps of maps in the inner zipper. If you take it out when you get home, your trip will be saved in your bag.
■ 4) As the “core of your outfit” Focus on bags made of good materials rather than flashy clothes. Coordination becomes easier and the overall impression becomes more mature.
How to enjoy changes over time ── A world where scratches become valuable
Waxed canvas has creases and scratches that give it its "expression." Natural cowhide leather has a luster and depth that gives it a sense of dignity. These two things grow at the same time, but the same changes never occur twice.
・Wrinkles on the canvas = your line of movement ・Gloss on the leather = your movements
In other words, the more you use it, the more your life becomes engraved on the bag. The value of this one-of-a-kind item is the essence of this backpack.

Notes on delivery time and packaging









Color transfer on leather products may occur due to the characteristics of the leather and dye, friction, etc. However, with proper measures and care, color transfer can be prevented.

1. Characteristics of color transfer on leather products
Color staining on leather products, despite its beautiful appearance and luxurious feel, can cause unexpected problems for owners. This phenomenon occurs primarily as a result of the natural material properties of the leather, the nature of the dyes used, and physical friction.
Color transfer due to the natural material characteristics of leather
Leather is a natural material, and its ability to absorb water and retain dyes contributes to color transfer. Especially in new leather products or products that have been treated with oils or waxes that have not been soaked in sufficiently, the dye can easily dissolve when it comes into contact with liquids such as moisture or sweat, making it easier to transfer the color to other substances.
Color transfer due to dye characteristics
The dyes used in the manufacturing process of leather products are intended to improve their brightness and durability, but some dyes have the tendency to transfer color when they come into contact with other materials. This tendency is especially noticeable when exposed to moisture or direct friction, increasing the risk of color transfer.
Color transfer due to friction
Friction between leather products and other substances that occurs during daily use is one of the main causes of color transfer. In particular, when wet leather products rub against clothing, furniture, etc., pigments tend to transfer. Light-colored leather products and products with soft leather textures tend to be more susceptible to this phenomenon.
Understanding these characteristics is essential to minimizing the risk of color transfer when choosing leather products and in everyday use. With proper precautions and care, you can preserve the beauty and functionality of your leather products over the long term.
2. Measures against color transfer on leather products
Color staining on leather products may seem like an unavoidable problem, but you can greatly reduce the risk by taking preventive measures. Below are some effective measures to prevent color transfer.
Precautions when handling new leather products
New leather products are particularly susceptible to color transfer, so care must be taken during the first few uses. It is important to avoid contact with brightly colored clothing and furniture, and if it gets wet from rain or sweat, dry it quickly. When drying leather products, avoid direct sunlight and heaters, and allow natural airflow to dry. This allows for quick drying while minimizing damage to the leather.
Avoid friction with existing clothing and furniture
When using leather products, be careful of color transfer due to friction with other clothing or furniture. Especially if you're pairing your new leather bag or shoes with brightly colored clothing, it's a good idea to take precautions to avoid chafing. For example, placing a scarf between your bag and clothing is effective.
Avoid moisture and store properly
Moisture is a major factor that promotes color transfer on leather products. When storing leather products, choose a location with low humidity and good ventilation, and if possible, use a desiccant such as silica gel to reduce moisture. You can also protect your leather products from dust and direct friction by using a storage bag or box specifically designed for them.
By implementing these measures, you can significantly reduce the risk of color transfer on leather products. Daily care and proper storage are the keys to keeping your leather products looking beautiful for a long time.
3. How to care for leather products to prevent color transfer
Proper care is essential to keep leather products beautiful and long-lasting. Preventing color transfer is an important part of this. Below, we will specifically introduce how to care for leather products to prevent color transfer.
Using cleaners and conditioners specifically designed for leather products
Keeping leather products clean is very important to prevent color transfer. Use a commercially available leather cleaner regularly to gently remove dirt and excess dye from the surface. After cleaning, apply a thin, even layer of conditioner made specifically for leather products to help fix the dye while keeping the leather supple. This reduces the risk of discoloration of the leather itself and color transfer to other objects.
Appropriate use of waterproofing spray
By applying waterproof spray to leather products, it is possible to prevent color transfer due to water and moisture. However, not all leather products are suitable for waterproofing, so always test on a small area and follow the product instructions before use. Waterproofing spray is effective when applied before going out on a rainy day or before using new leather products for the first time.
Keep leather supple with regular moisturization
When leather dries, it becomes hard and the color transfer is more likely to occur due to friction. Regular use of a leather moisturizer or conditioner will help maintain leather flexibility and prevent color transfer. Moisturizing is important not only to extend the lifespan of leather products, but also to maintain their beautiful appearance.
Practice proper storage methods
It is important to store leather products properly even when not in use. Store in a well-ventilated place away from direct sunlight, high temperature and humidity. Also, avoid direct contact between leather products to reduce the risk of color transfer. By putting it in a leather bag, you can protect it from dust and scratches.
By practicing these care methods, you can greatly prevent color transfer on leather products and maintain the beauty and functionality of your products for a long time. Think of regular care as an investment for a long-term relationship with your leather product, and treat it with love.
Summary
Color transfer on leather products may occur due to the characteristics of the leather and dye, friction, etc. However, with proper measures and care, color transfer can be prevented.
You can prevent color transfer on leather products by taking measures such as avoiding friction with new or existing clothing or furniture, and avoiding moisture. You can also maintain the beauty of your leather for a long time by using cleaners and conditioners made specifically for leather products.
Leather products have a sense of luxury and durability, and are popular as fashionable items. In order to use your leather products for a long time, take measures to prevent color transfer and take proper care of them.

The secret to achieving both price and quality
Realized with COWMONO
"Even if the price is low, we don't compromise on quality."
To achieve this balance, we are focusing on cost cutting and quality improvement.
1. Thoroughly eliminate intermediate costs
Compared to the general distribution process of "factory -> trading company -> manufacturer -> wholesaler/retailer -> consumer", COWMONO has a direct connection from "factory to consumer".


Direct sales model completely eliminates extra costs. However, there are some challenges with shipping directly from the factory.
Issues with factory direct shipping
- Length of delivery period
- Confused about unfamiliar packaging
About delivery period
COWMONO has set up overseas warehouses in order to pursue cost reduction to the utmost.
As a result, it will take approximately 10 to 20 days for delivery, but we hope that you will enjoy this waiting time as part of your expectations.
About packaging
Since the item is shipped directly from an overseas warehouse, the packaging will be simple. You may feel confused when using our products for the first time, but we have absolute confidence in the quality of our products.
*Image of home delivery plastic bag
However, we do not compromise on quality.
Many luxury brands are particular about their packaging, passing the cost on to the consumer.
However, COWMONO pursues ``providing high-quality products at amazing prices.''
2. Reduction of web operation costs
Many online retailers spend a large amount of money on EC site management and SEO consulting.
However, COWMONO operates without any of these costs.
3. Original sales on your own website
We sell only on our own site, not on major platforms, and avoid unnecessary fees.
4. Careful selection of products
By handling only carefully selected products, we reduce costs while maintaining our commitment to quality.
Commitment to low-priced, high-quality products
Changing the common sense that "high price = high quality". That is the goal of COWMONO.
