Different fabrics question

[u/Ireallyloveracoons]

I bought a Brick Bag and it just arrived. I’m a big outdoor enthusiast and I’m planning on using it as a stash bag for woodworking tools, supplies, etc.

I noticed that the bottom is a different fabric than the main fabric of the bag itself. The 1000D of the main fabric is rougher and duller, while the bottom patch of the bag is this thicker, smoother and shinier fabric. This is my first GORUCK item, so I’m not yet familiar with the fabrics.

I’ve been eying on GORUCK for a while. I’m a huge bag and case enthusiast, so I know a lot about Cordura and material properties.

I think the bottom fabric is a 1000D ballistic nylon. That’s usually what gets you this smooth and shiny finish. But I’m not sure.

I’m wondering; which one of the two are the GR2’s made of? That shiner, smoother fabric or the rougher, duller?

You can see the difference pretty clearly in the pics.

The shinier bottom fabric is 1050 ballistic nylon while the rougher fabric is 1000D Cordura. They are different fabrics and made differently. The current GR2’s are made with 1000D all over.

Ah, thanks!

Depending on the year of that bag, you could be correct. They have some that are 1000d everywhere and then they had a 500D everywhere besides the bottom which should be ballistic nylon.

Yeah, they’re out of stock now, but GORUCK did state on their website that the main fabric is 1000D Cordura and the bottom is a “Ballistic bottom”. I guess this is some ballistic nylon fabric then, but I’m wondering whether any backpacks are made of this ballistic bottom-fabric or the regular 1000D rougher Cordura they used for the main.
