Our first order was 300 sets in a brand color nobody could match — a deep red that every other factory turned into a muddy brown the moment it hit white mesh. I'd been burned twice already, so I wasn't expecting much.
What came back looked dyed into the fiber. Shrinkage came in under 1.5%, the AATCC 61 wash test hit grade 4–5, and the burst test on the interlock read well above our 40 lbf floor. I'd asked for those numbers in writing for months and never got them.
The reorder a season later is what sealed it. Same 300 sets, same shade, same panels, zero re-sampling — they kept the RIP file and dye recipe locked from day one. When a kit comes back identical a year later without anyone asking a question, the supplier stops being a worry.
