Definitions
- GSM
- Grams per square metre. A measure of fabric weight.
- Knit
- Fabric made from interlocking loops of yarn.
- Woven
- Fabric made from yarns crossing at right angles.
GSM is a clue, not a verdict
Weight alone does not describe warmth, stretch or durability. Fibre, yarn and structure all contribute, so ask for the measured value and a physical sample.
A practical example
Practical example. Two quotes list the same GSM. One is brushed on the inside and one is not. Compare a physical sample before choosing.
