Fabric weight (gsm)
GSM means grams per square metre. Higher GSM usually means a thicker knit, more warmth, and better wind resistance.
Lower GSM usually feels lighter, dries faster, and is better for high output.
Fibre diameter: 17.5µm
Fibre diameter (microns)
Microns measure the thickness of each merino fibre.
Smaller microns usually feel softer against skin because the fibres bend more easily. Larger microns usually feel firmer and can be more rugged for outer layers.
| Fibre | Thickness |
|---|---|
| Ultra fine | 15µm |
| Super fine | 17.5µm |
| Fine | 20µm |
| Mid-weight | 22.5µm |
| Coarse | 25µm |
| Human hair | ~70µm |
Merino's natural odour resistance means a simple air between wears is almost always enough, and the less you wash it, the longer it lasts.
