Fabric specification tip: GSM measures the mass of fabric per square meter. It does not directly determine thickness, softness, durability, or quality. Those properties also depend on fiber content, yarn, knit or weave construction, finishing, and fabric structure. Reference examples are approximate; the appropriate weight depends on the intended garment.
