35 — What we learned from writing about GSM.
We have spent the last several months writing about fabric weight. What GSM means. What ring-spun cotton does differently from open-end. What loop-back fleece is and why it matters at 400gsm. What garment dyeing does to cotton that nothing else can. We wrote it because the questions were being asked and we had the answers. We also wrote it because writing forces precision.
Here is what the process confirmed.
Most brands cannot answer these questions about their own products. Not because the information does not exist — it does, somewhere in a factory specification sheet — but because they have never needed to. The customer was not asking. The customer is asking now. The vocabulary has shifted. GSM, ring-spun, loop-back, garment-dyed — these are terms that appear in consumer conversations in 2026 in a way they did not three years ago. The brands that built to a specification before the customer knew to ask for one are in a different position from the brands scrambling to retrofit a narrative onto a product that was never built to support it.
We are in the first position. We specified 400gsm ring-spun cotton loop-back fleece before we wrote a single post about what that meant. The writing did not create the specification. It described one that already existed. That distinction matters more than it might appear to. A brand that builds its product around its content is a content brand. A brand that builds its content around its product is something else.
What the writing changed is the standard we hold ourselves to in how we describe what we make. Precision in language about fabric is not marketing. It is accuracy. When we say 400gsm, we mean 400gsm — not approximately, not at the heavier end of 380gsm. When we say ring-spun, we mean the yarn was produced by continuous twisting before spinning, not that the cotton is soft and the label says premium. The writing made us more precise about the claims we make, because we were writing for a reader who now knows the difference.
That reader is the customer HQ 001 was built for. We did not know that when we started. We know it now.
