Among the fabrics made by INVISTA in the United States, "CORDURA® Ballistic Nylon" is used in outdoor and other scenes where durability is required. With its robust specifications, strong enough to be used in bulletproof vests, it boasts one of the strongest classes of fabrics. Despite its military specifications, it is utilized in a variety of general products.
Ballister Nylon is a Japanese-made fabric created domestically with such robust military specifications. Moreover, it is made even stronger by using a thicker thread, 2520D, which is thicker than general ballistic nylon on the market.
This fabric, boasting one of the strongest levels of strength among domestically produced materials, truly showcases its appeal when integrated into a product like a bag, exceeding its catalog specifications. Let's explore the charm of Ballister Nylon.
Fabric strength is thread strength
The material used in WONDER BAGGAGE bags, Ballister Nylon, is one of the strongest fabrics produced in Japan.
The threads used to make the fabric are "ultra-strong 66 nylon threads" originally used for military purposes in the United States, which are then twisted together. As mentioned earlier, the denier count (D), which indicates thread thickness (mass), is 2520D. To show just how remarkable this number is, we've prepared a magnified comparison image with a common 420 denier nylon. You can immediately see the overwhelming difference in the size of the thread particles.
The strength of the threads used to create a fabric directly translates to the strength of the fabric itself. Furthermore, its appearance also influences the product's look, creating a unique presence.
Typical nylon fabrics range from thin at 210D, common at 420D, and thick at around 1000D. A value of 2520D indicates six times the strength compared to regular nylon (420D).
Ballistic nylon typically ranges from 1680 to 2100D, which is 4 to 5 times stronger than standard nylon. Ballister Nylon, exceeding these figures, demonstrates extremely high strength not only in Japan but globally.
(*) Denier: 1D represents the mass of 9000 meters of thread in grams.
Specification Introduction
Ballister Nylon is manufactured by a Japanese fabric maker and undergoes various comparison tests at public institutions.
As you can see from the tables, Ballister Nylon boasts several times the strength compared to general nylon materials (420 nylon ox). Its robust strength, even adopted for bulletproof vests, is truly remarkable. Furthermore, as a bag brand, its excellent resistance to melting from heat, which is a weakness of nylon, cannot be overlooked.
Data shows that in a cigarette press test at approximately 800 degrees, it withstood penetration for 30 seconds. We believe these various specifications will help you understand that it is a material that can be used with confidence.
Royal Navy
The navy color of Ballister Nylon used by WONDER BAGGAGE is the brand's original Royal Navy. While regular in-line navy colors often have a strong green tint, this Royal Navy has a slight reddish hue, giving it a dignified impression.

Nylon that ages gracefully
Ballister Nylon is manufactured in Japan. The weaving density and precision during the fabric production process are high, giving the fabric itself firmness and body, which in turn provides high self-standing capability when made into a bag. Bags made with such refined techniques and materials create a luxurious appearance.
Furthermore, Ballister Nylon is a rare nylon material that undergoes aging, gradually softening and becoming more familiar to the user with continued use.
