Weight is one fact. Construction is the object.

GSM means grams per square metre. It describes fabric mass over area, not softness, fibre quality, seam strength, warmth, or lifespan by itself.

A heavier knit can feel structured; a lighter one can drape or layer better. The useful number is the verified weight of the exact blank or fabric used for the object, read together with fibre content and construction.

Collar recovery, seam type, panel alignment, cuffs, hems, and reinforcement at stress points often matter more than a headline weight. All-over-print pieces also depend on how artwork crosses panels and seams.

• Check the exact material composition and care instructions.
• Compare garment measurements, not only the size letter.
• Treat supplier tolerances and placement variation as production facts, not surprises.

Screen print, direct-to-garment print, embroidery, transfer, and all-over print behave differently. Fine line work, dense fills, stretch, texture, and garment colour all affect which process is appropriate.

3TIL9 records the intended artwork role and production route per object. A physical sample remains the strongest evidence for colour, hand-feel, placement, and wash behaviour before commerce opens.

A product page should distinguish verified facts from open production checks. If weight, origin, sample approval, or a responsible-party detail is unknown, the honest state is to omit the claim or mark it unresolved-not to infer it from a similar garment.
