Inherent or treated FR fabric for long rotations?
Inherent FR fabric gets its protection from the fiber and usually feels lighter for its rating, which matters on 14-day rotations in Permian heat; treated FR fabric is cotton-rich, cost-effective and comfortable when laundered correctly. Both can carry certification when documented.
| Fabric | Typical weight | Notes |
|---|---|---|
| FR-treated cotton | About 200–270 GSM | Familiar feel, durable, most cost-effective |
| FR-treated cotton-nylon | About 190–240 GSM | Better abrasion resistance for rough work |
| Inherent FR blends (aramid, modacrylic) | About 150–220 GSM | Lighter for the rating; protection cannot wash out |
