Understanding GSM
GSM refers to the weight of the fabric per square meter. But this number tells more than just mass. It speaks to density, structure, and a way of being.
A lightweight fabric disappears. A dense fabric remains.
GSM is not just technical data. It is a physical sensation.
Why it changes everything
Two garments may look identical. Once worn, they no longer tell the same story.
A lightweight fabric accompanies. A dense fabric structures.
What GSM transforms
- The garment's silhouette
- The presence on the body
- The immediate perception of quality
- The ability to last
A good garment doesn't float. It holds.
The different levels
GSM allows you to immediately position a piece. Not in absolute value, but in intent.
120 – 160 GSM
Very light. Subtle, but often fragile.
180 – 220 GSM
Standard. Functional, rarely striking.
240 – 300 GSM
Good structure. The garment begins to exist.
300+ GSM
Dense. The material becomes a central element.
Above a certain threshold, it is no longer just fabric. It is a structure.
Common mistakes
GSM is often misinterpreted. It is reduced to a number, whereas it also depends on the fabric construction.
To avoid
- Confusing weight with quality
- Choosing a dense fabric that is poorly constructed
- Neglecting the feel when worn
A good GSM should never be restrictive. It should accompany while providing structure.
The role of French Terry
French Terry introduces an essential nuance. Its looped structure allows for density without trapping the body.
It offers a rare balance: a material that has substance, but breathes.
What makes it unique
- Natural breathability
- Controlled density
- Prolonged comfort
- Living structure
470 GSM: another dimension
At 470 GSM, we enter a different realm. We are no longer talking about just a garment. We are talking about material.
The fabric no longer follows the body. It defines it.
470 GSM is the point where the material becomes the starting point.
Combined with French Terry, this level of density creates a rare balance: a strong structure, but never rigid. A presence, but never a constraint.
A piece that holds, breathes, and evolves.
Choosing the right level
Everything depends on the intent. A light garment accompanies a moment. A dense garment accompanies you over time.
Benchmarks
- 150 – 200 GSM: light
- 220 – 300 GSM: daily wear
- 300+ GSM: structured
- 400+ GSM: signature
It is in this final category that the garment changes its nature.
A different idea of clothing
Choosing a high GSM is not about choosing more. It is about choosing better.
It is deciding that the material should carry the piece. That the garment should last. And that it should exist fully.
