Due to their synthetic makeup nylon bags can be extremely durable. However, it’s worth pointing out that, as with any material, there are varying degrees of quality. For example, at Carl Friedrik our nylon is sourced from a leading supplier in Korea. Meaning we can offer a lifetime guarantee on these bags. Lower-quality nylon will lead to a far lower shelf life.
The strength of a nylon bag will also depend on its construction. Take a bag with reinforced seams and zips — it will tend to hold up better than one that doesn’t have these design features.
Hiking backpacks and military equipment are typically made from tougher ballistic nylon given their purpose. As we mentioned earlier, ballistic nylon is stronger than nylon canvas: this is due to its higher denier and tighter weave. The denier of nylon determines the thickness of individual threads, so a thicker thread creates a stronger fabric. A tighter weave also adds to the strength of the material as the fibres are woven more closely together.
If the goal is to produce a sleek everyday bag, however, nylon canvas represents a better bet because it’s lighter and more fluid.
Proper maintenance and care, such as cleaning and avoiding overloading, will help a nylon bag to stay in prime condition for longer. The material is fairly resistant to water, heat and some sunlight, but extreme heat, chemicals, dyes and intense UV exposure can cause nylon bags to fade in colour and weaken.
