Poly-cotton twill, ripstop, Cordura, meta-aramid FR, hi-vis polyester knit, moisture-wicking interlock — each solves a different problem. This category sorts through the working spec language of fabric selection for custom workwear: what each fabric actually does, when it earns its premium, and when to step down to a cheaper alternative without compromising program quality.
