# Fabric Weight — Boring Label Textile Glossary

*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.

- **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.
- **Opacity** — Higher fabric weight means more fibre per area, which means no see-through embarrassment — particularly important for white and light colours.
- **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.

- **180** GSM — Consistent across all colours and sizes

## Fabric weight — your questions, answered.

Understanding how fabric weight affects garments.

**Is 180 GSM considered heavyweight?**

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.

**Why not offer multiple weights?**

We'd rather perfect one weight than offer a mediocre range. 180 GSM in Supima cotton is our answer to the question 'what weight works best for a premium everyday t-shirt?' We tested extensively. This is it.

**Does fabric weight affect breathability?**

Slightly. Heavier fabrics are marginally less breathable, but cotton's natural moisture-wicking properties compensate. At 180 GSM, breathability is excellent for everyday wear.

**Is GSM the same as fabric weight?**

Essentially, yes. Fabric weight and GSM are the same concept — the mass of a fabric per unit area. GSM (grams per square metre) is simply the most internationally standardised unit for expressing this value. You may occasionally see oz/yd² (ounces per square yard) in North American specifications — 1 oz/yd² is approximately 33.9 GSM.

**How does fabric weight affect how a t-shirt looks on the body?**

Lighter fabrics (under 150 GSM) tend to cling and ripple, revealing body contours more obviously. Mid-weight fabrics (160–200 GSM) hold a cleaner silhouette off the shoulder and drape more evenly. Heavier fabrics (200+ GSM) create a more structured look — they hold their shape but can feel warm and slightly stiff in high temperatures.
