what's the nylon fabric:

•  Nylon is a class of synthetic polyamide materials made by copolymerizing dicarboxylic acids with diamines. They can be moulded into a variety of articles, such as combs and machine parts and used for bristles or be spun into yarn.

Nylon's special characteristics:

• Variation of luster: nylon has the ability to be very lustrous, semilustrous or dull.
• Durability: its high tenacity fibers are used for seatbelts, tire cords, ballistic cloth and other uses.
• High elongation
• Excellent abrasion resistance
• Highly resilient (nylon fabrics are heat-set)
• Paved the way for easy-care garments
• High resistance to insects, fungi, animals, as well as molds, mildew, rot and many chemicals
• Used in carpets and nylon stockings
• Melts instead of burning
• Used in many military applications
• Good specific strength
• Transparent to infrared light (−12dB)

what's Ballistic nylon:

The original specification for ballistic nylon was an 18 ounce nylon fabric made from 1050 denier high tenacity nylon yarn in a 2x2 basketweave. Today the term is often used to refer to any nylon fabric that is made with a "ballistic weave", typically a 2x2 or 2x3 basketweave. It can be woven from nylon yarns of various denier such as 840 denier and 1680 denier. Denier refers to the weight, not the strength, of the fabric. Laboratory testshave been run and the double weave 1050 denier fabric is the strongest and most durable fabric for its denier weight level. The 1680 denier looks very similar to the 1050 when it is new, but it is actually not as strong as double weave 1050 denier and gets fuzzy as it wears.As it resists abrasion and tearing, ballistic nylon is typically used for luggage and in the bottom of bags made of a lighter nylon or other fabric. Ballistic nylon is hard to dye, so it is often found in black or similar dark colors.

what's the difference between nylon fabrics and polyester:

 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.
