Checked the flag patch option right at checkout and it was exactly the Thin Red Line design I wanted, no confusion about what I was adding. The stitching is tight and the colors are vivid, so it should hold up well on my gear bag.
The thin red line stands out nicely against the black backing, and it attaches securely without any loose threads. I added it to my order as a customization option and it arrived exactly as shown.
The patch stitching is clean and the colors pop exactly like the listing photo showed. I added it to my order for a custom build and it arrived packed flat with no creases or loose threads.
