I’m looking for a new backpack and I would like to buy the one that will last me the longest.
I’ll list the two backpacks and each of their build fabrics
1350 cubic inches
420-denier nylon, 1680-denier ballistics
1600 cubic inches
600-denier polyester, 420-denier Velocity nylon
Now, I know what nylon and polyester is; I’ve heard that generally speaking, nylon tends to be the stronger of the two fabrics.
However, I have never heard of “Velocity nylon” or “denier-ballistics” so could someone explain where those two fabrics stand in terms of their durability?
To be fair- I’ve never heard of Velocity… but here we go.
Ballistic nylon is a stronger weave of material. It also carries a lower friction coefficient thus can resist abuse of dull objects better- preferably flat. Ballistic nylon is common on softgoods that see higher abuse-esq situations… like backpacks sliding on the floor, luggage, roller hockey pants- stuff like that.
Polyester and Nylon can share very similar characteristics in fabric. Nylon is generally more expensive- and better in life changing situations… everything else in my opinion could be chalked up to preference.
Of course the difference at the “backpack” level has me thinking that this post wasn’t worth my time in cost it took to write- but I hope you liked it.
Go for pack #1. 420D is still fairly burly, but much lighter weight than ballistics. I personally don’t like the look of ballistic nylon in general, but if you are looking for durability, it doesn’t get much better.
Not typically but it depends on the 600Ds backing.
Nylons are typically stronger than comparable weave Polyesters
BUT Polyesters with a 2xPU or 2xPVC backing are more durable than comparable Nylons and much more inexpensive, but heavier weight and more inflexible.
and while the difference between the 420 D Nylon and 600D poly is an extra 180 threads per inch, the backing on the poly can make a huge difference in its cost and durability.
Velocity is a generic name of a weave (like Ballistic, Twill, Oxford, Ripstop, Diamond Rip stop, Diaper ripstop etc) that can be on a bias from Ballistic (ie ballistic is vertical/horizontal, Velocity is on the 45Âº) and typically runs around 600D.
at least thats what the Korean sample book I have in front of me shows…
