What does g/m² mean in rainwear fabric?
Distinguish fabric mass from finished raincoat weight. Read 180 and 400 g/m² examples in the context of fabric area, size and coating.
Quick answer
g/m² is the mass in grams of one square metre of fabric. It is not the weight of the finished raincoat. Different sizes and cuts need not weigh the same even when their fabric mass matches.
Compare figures using the correct unit
The published 400 g/m² for Y-7600 and 180 g/m² for TR-1000 describe their fabrics. Hood, zip, lining and total fabric area contribute to finished weight. Multiplying fabric mass by unit quantity is therefore not a valid way to calculate shipment kilograms.
A square-metre calculation
A 0.5 m² piece of 400 g/m² fabric corresponds to 200 grams of fabric mass. This example does not establish the area required for a coat and excludes cutting waste and accessories. Keep fabric mass separate from net and gross shipment weight.
- Record the figure in g/m² with its model code.
- Request separate evidence for strength or breathability.
Current model data and technical sources
This table uses the same data as product pages and model TDS documents. Fabric mass is in g/m², not finished product weight. Missing fields require confirmation.
| Model / collection | Materials and fabric mass | Sizes / packing | Source |
|---|---|---|---|
| Y-7600 | Fabric: PVC-coated fabric · 400 g/m² | XS–3XL 20 units | Model TDS Care instructions |
| TR-1000 | Fabric: PU-coated fabric · 180 g/m² | XS–3XL 20 units | Model TDS Care instructions |
Is a higher fabric mass always better?
No. Assess cut, movement, composition and required test results together. Fabric mass alone is not a quality ranking.
