Materials: what 260 gsm heavyweight cotton actually means
Fabric weight is the most quoted and least explained number in clothing. Here is what it means, and what it changes when you wear the garment.
Grams per square metre
GSM is the weight of one square metre of fabric. A standard t-shirt sits between 140 and 180 gsm. Anything above 220 gsm is generally described as heavyweight.
OBJECT_001 is 260 gsm. You feel it immediately at the shoulder and the hem: the fabric hangs rather than clings, and the neckline keeps its circle.
Combed, ring-spun cotton
Weight alone is not quality. The yarn matters more. Combed, ring-spun cotton removes short fibres before spinning, which produces a smoother surface, less pilling, and a print that sits flat.
Shrinkage and care
Heavyweight cotton is pre-shrunk, but expect a small amount of movement on the first wash. Wash cold, inside out, and dry flat or on low heat. Do not iron directly over the transfer print.
Cared for that way, the garment holds its shape for years rather than seasons.
