There are a lot of materials that are used to manufacture travel backpacks. One of them, is the ballistic nylon.

Let's start from the basics. What is the nylon, and what makes it ballistic? Ballistic nylon is used to refer to any nylon that has a “ballistic weave” which is typically a 2×2 or 2×3 basketweave.

Its origins go all the way back to the Vietnam war where it was made by DuPont for exclusively military applications. It was originally developed as an anti-fragmentation ballistic jackets for the military, which is where the term “ballistic” come from.

It consisted of multiple layers of the fabric laminated together to help to protect the military from these explosive devices. But as it turns out, while it's great for deflecting minor shrapnel and debris, not so much so for bullets.

This is why the military moved to another material, KEVLAR, and ballistic nylon found its way in the consumer market because of its excellent strength and its slick finish.

What are the different types of Ballistic Nylon?

While ballistic nylon has its origins way back to the end of WWII and the Vietnam War, there are so many variants nowadays that are used in a wide range of applications, as we said before. Like the micron count in merino wool, how you judge a ballistic nylon is down to the denier counts.

But, what does ‘denier' mean? Denier (just “d” for short) is the term used to define the fiber thickness of individual threads used to create a fabric. The higher this value is, the heavier the final product is.

Also, the higher this value is, the fabric tends to be sturdier and more durable. On the other hand, the lower the denier count is, the textile tends to be sheer, more silky, and softer. The most common denier counts for ballistic nylon are:

· 1050d

· This was the original count for the first fabric made in the times of the Vietnam War. This material is advantageous when it comes to backpacks. It is very light and doesn't damage clothing or other fabrics that get in contact with it. It is excellent for women because it doesn't collect hair neither.

· 840d, 525d, 210d

· As mentioned, the lower the denier count, the lighter it gets. 525d is great for daypacks like the TOM BIHN Synapse 25 that you're probably not going to be abusing as much. 210d is perfect for stuff that don't see a lot of abrasion, like this TOM BIHN Stuff Sack.

· 1680d

· While a larger denier count might sound like it's a better fabric, 1680d is woven from a large single yarn, rather than two plies of 1050d. This gives the appearance of a two-ply fabric, but actually ages poorer and fuzzes out at abrasion points. It's not surprising that the 1680d is mostly made in Asia.

Ballistic Nylon vs CORDURA

To determine which is better, you need to know the differences. There are two significant technical differences between the two. Ballistic nylon made of “filament” yards which are smooth and slick while CORDURA are texturized, which makes them slightly fuzzy like natural fiber.

CORDURA has higher abrasion resistance, while ballistic nylon has higher tear resistance.The abrasion resistance and tear stretch is higher than what most consumers need. Unless you are taking it out to fight wars in the field, it's unlikely you'll ever feel the difference.

The only tangible difference that most can feel is the appearance. Because ballistic uses a two-ply weave, which means two yarns woven into one, they are less smooth than CORDURA and carries a rugged texture.

Ballistic is also harder to dye, which is why you mostly see black ballistic nylon backpacks.

Basically, ballistic nylon are more nicer for travel bag. Cordura nylon are more better for military backpack.

Ballistic Nylon vs Ripstop Nylon

The main difference between the two is mainly in the way that the fabric is weaved. Ripstop is interwoven at regular intervals in a crosshatch pattern, which allows it to stop rips, hence the name.

What Ripstop excels in over ballistic nylon is its strength-to-weight ratio and that it has the ability to prevent the spread of small tears.
