The ballistic nylon will be a higher denier (thickness of the thread). Also will be shiny/glossy compared to the matte finish of polyester. Ballistic nylon will be much more durable and much less likey to tear or scuff. You can get higher denier polyester (900, 1200, 1800) which will be better for wear and tear. The price will reflect this however as 600d poly is low to mid price point whereas the others are higher.

Micro ballistic nylon is typically stronger and more durable than 1680-denier polyester and nylon fabrics due to its tightly woven structure and higher abrasion resistance. While 1680-denier fabrics are robust and commonly used for heavy-duty applications, micro ballistic nylon offers superior tensile strength and resistance to wear and tear. This makes it a preferred choice for high-performance gear and tactical applications.
Nylon is more durable than polyester. Also, when comparing 840 denier to 600 denier of the same fabric, the 840 denier is thicker, rougher, more coarse and stronger than the 600 denier. So, on both counts, the 840 denier nylon is more durable. If you look at the following link, the tan soft dog crate is made of 600 denier polyester and the colorful soft dog crates are made of nylon.
"2400 Denier Polyester and 900 DenierMicro-Polyester fabric"
Though I haven't used either of these myself but EVA- reinforced polyester will be the better option
A 1260 American made Ballistic Nylon is the best you can get at this time but they are coming up with new fabrics all the time. A 2520 Foreign made ballistic nylon is not a bad choice either.
800D fabric refers to a durable polyester material with a denier rating of 800. Denier is a unit of measurement that indicates the thickness of the fibers used in the fabric; higher denier numbers generally indicate stronger and more durable fabrics. 800D fabric is commonly used in applications such as backpacks, luggage, and outdoor gear due to its resistance to wear and tear, water, and abrasion. Its robust nature makes it suitable for heavy-duty use while remaining relatively lightweight.
The thickness of 600 denier polyester fabric can vary depending on the specific manufacturing process, but it typically measures around 0.5 to 1.0 millimeters. Denier refers to the weight of the fabric, with 600 denier indicating a medium-weight material that is durable and commonly used for bags, outdoor gear, and upholstery. The thickness can also be influenced by the weave and finish of the fabric.
I am assuming you are talking about a fabric made from either 1200 or 600 denier yarn. The thickness of the yarn in 1200 denier is twice that of 600 denier, which also implies the fabric will be rougher and ofcourse stronger. If you are looking for strength, 1200 is better. If you want a smoother finish fabric, choose the 600 denier. Hope this helps. Deviprasad
Denier polyester is fabric and the higher the number, the thicker and stronger it is. 210 would be thin like silk.
Denier is a unit of weight indicating the fineness of fiber filaments and yarns that are woven together to make up the ballistic nylon.
is 330 deniers nylon better than 500 D cordura ? 100 D cordura ? (for backback with audio gear) thanks so much
