Fabric Weight
Fabric weight refers to the mass of a fabric per unit area, typically measured in GSM (grams per square metre) or oz/yd² (ounces per square yard). It determines a garment's drape, warmth, opacity, and durability.
Understanding the Term
More than just heavy or light.
Fabric weight encompasses the combined effect of yarn count, fibre density, and knit or weave construction. Two fabrics can share the same GSM yet feel entirely different if one uses fine yarn at high density and the other uses coarse yarn at lower density.
For t-shirts, fabric weight is the specification consumers can most easily perceive. Pick up a 140 GSM tee and a 200 GSM tee — the difference is immediate. But the number alone doesn't tell you about softness, drape, or longevity. Those depend on fibre quality.
Fabric weight also determines seasonality. Lighter weights (120–150 GSM) suit hot climates and layering. Midweights (160–200 GSM) work year-round. Heavyweights (220+ GSM) are autumn/winter staples. Our 180 GSM sits in the year-round sweet spot.
Why It Matters
How fabric weight shapes the wearing experience.
The number you can feel.
01
Seasonal Versatility
180 GSM works in air-conditioned offices, moderate winter days, and summer evenings. It's the weight that doesn't demand a season.
02
Opacity
Higher fabric weight means more fibre per area, which means no see-through embarrassment — particularly important for white and light colours.
03
Longevity
Denser fabric resists wear from friction, stretching, and repeated washing. More material means more margin before the fabric thins.
Our Standard
180 GSM — deliberately chosen.
We didn't arrive at 180 GSM by accident. Two years of sampling from 140 to 240 GSM with Supima cotton led us to the weight where opacity, drape, comfort, and durability converge. Every colour, every size, every batch hits the same target.

Understanding how fabric weight affects garments.
No. 180 GSM is midweight. Lightweight is under 150 GSM, midweight is 160–200 GSM, and heavyweight is 220+ GSM. Our 180 GSM is the upper end of the comfortable year-round range.
