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: 20.5µm
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.

Ordered 3 in XL and all 3 garments completely different, not just a small amount as one looked like a child’s garment
Shocking quality
We are really sorry to hear about your experience, and completely understand your disappointment. This isn’t the standard we aim for, and the sizing inconsistency you’ve described is not acceptable.
We’ve already set up your free return, and we’ll review the garments as soon as they arrive back with us to understand what went wrong. Your feedback is important, and we’ll use it to improve our quality checks.
Love pretty much everything about this zip hoody and wear it all the time. My issue is bobbling. Just from wearing the whole top is now completely covered in bobbles. This really takes away the quality look the garment had when it arrived. Was going to get another but it doesn’t look good for long enough. Shame.
Thank you for your feedback!
We're glad to hear you love the hoody and wear it often. Sorry to hear about the bobbling — it’s a natural trait of wool, but there are ways to minimise it. Washing with coarser fabrics like denim (with zips closed) can help remove loose fibers and keep it looking great.

Zip is too riigid so it causes the front of the garment to buckle and pout. Sa result it does not follow the body curve.
Love the fit - sleeves long enough for the tall and lanky. Well made and comfortable but the material is of poor quality. Only 2 weeks old and is pilling horribly especially at the cuffs, compared to my wife's Smartwool version which is 2 years old and zero pilling. Grateful to have purchased this on a 50% off sale - I would not pay full price for an item that is not likely to last a year and as a first time customer it makes me question purchasing any additional items.
Sorry to hear about the pilling, that's not the experience we want for you. A fabric shaver will help in the short term, but all our products carry a 2-year warranty so please reach out to our team and we'll be happy to help.
Lovely hoodie, light weight enough for my morning dog walks
Yet another fantastic merino piece in my wardrobe.
I picked up the IsoSoft 240 Hoodie and cannot be more happy with it. Soft and warm and stylish!! A perfect fit.
Thank you for the review! Your kind comments are greatly appreciated, and we are so pleased to hear that you like the hoodie!
Best wishes,
The Isobaa Team
For an active lifestyle. Tighter fit. I wish it was 100 % wool but i love the fit over other products. My life is a hike. I bike everywhere. I am 172, 62 kgs, athletic. I am happy with the fit since it doesn't leave room for windchills to go throught.
Thank you for taking the time to leave a review! It's great to hear that you're pleased with the hoodie, and that the tighter fit is protecting you from windchill. Our IsoSoft range is our Merino Blend range, where most of our other products are 100% Merino wool. For a similar 100% Merino alternative, we suggest looking at our 260 Casual Hoodie. It is lighter, but a bit warmer than the IsoSoft 240 Hoodie.
Please feel free to get in touch if you have any questions.
Kind regards,
The Isobaa Team
Soft, keeps me warm but not hot. Recommended
Thanks for the feedback and recommendation, Jenner! We're happy to hear that you're pleased with your purchase. Please feel free to reach out if you ever have any questions or require assistance.

well made and feels quality
but its not the best shape!
quite long in the body and tight under the pits makes it feel a bit awkward when wearing.
also, unless you wear with the hood up or not zipped up the top of the zip/collar canbe quite annoing
Thank you, Hugh, for sharing your feedback about our IsoSoft Hoodie. We appreciate your honest and valuable input. It's great to hear that you're mostly pleased with the hoodie. However, we are sorry to hear that the fit and some design aspects haven't met your expectations.
We take customer feedback seriously, and we'll certainly take your comments into consideration as we continue to improve our products. If there's anything we can do to immediately address your concerns, please don't hesitate to contact our customer service team.
Best wishes,
The Isobaa Team

Are you going to do the Isosoft 240 hoodies in black at any point??? :)
We don’t have any immediate plans to expand the Isosoft range, but we’ll pass your request on to our design team — thanks for the suggestion!
What's the size of Chest of Small? Thanks!
Hi Tao,
Please see the 'Garment Measurements' tab for product sizing information. The Half Chest measurement for size S is 51cm point to point when the garment is laying flat. This should fit someone with a chest of ~36 inches as per our size guide.
Kind regards,
The Isobaa Team
What's the % content of merino vs polyester? I always want to know this when buying merino products. Thanks!
Hi Charles,
This product has a blend of 50% Fine Merino Wool and 50% Recycled Polyester.
Kind regards,
