Fabric weight: 320gsm
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: 18.5µm
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.

I bought this primarily because of the very high collar on it, and as someone with a long neck who works outdoors I have to always rely on a neck warmer this time of year. As usual IsoBaa did not disappoint - this is a perfect mid-layer weight, the double thickness collar is stiff enough to stay up and keep my giraffe neck warm, and the colours look just like the photos. Yet another favourite piece of kit. Bonus points for the deep pockets items wont fall out of and the small zipper pockets feature.
P.s. I bought a medium so I could fit it over a few layers and it was perfect.
First Isobaa purchase (tempted after I purchased my husband a couple of jumpers for winter). Love the fabric, the colour and the little details. Its a great middle layer. I've used it for hiking and taking it with me skiing . I didn't realise it came with an elasticated bottom. I can see it's purpose but I'd prefer it without. I'd still buy another one in a different colour.
Great top. Love the colour combo (blue and lime) and the collar. Material has started pilling very slightly on the cuffs. Worn a few times but haven’t washed it yet.
