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.

Drop tail hem
A longer hem at the back gives you extra coverage where you need it most, whether you're moving, bending, or layering up
Layering system
Worn alone or tucked under a jacket, the slim collar sits neatly beneath outer layers, making this a versatile piece that earns its place in any pack
Natural merino
Naturally soft against the skin, moisture wicking, breathable and odour resistant, Merino is one of those rare fabrics that genuinely works harder the more you wear it
Proudly natural
Our Merino wool is ethically sourced from trusted Australian suppliers with a heritage dating back to 1857. We only use non-mulesed wool, working with partners who prioritise animal welfare and responsible land management.
Merino is a renewable, biodegradable fibre that naturally regulates temperature, manages moisture and resists odour, delivering reliable performance with a lighter environmental impact.

Nice top, seems to suffer as per another brand i use with cuff finishing - some loose threads . Strange as the hem is great.
All three tops I purchased fit lovely and are great. Highly recommend Isobaa
Just a nice fit
Outstanding design and Quality of their products!
Have purchased a number of Isobba products and they’re excellent - when it comes to Merino wool garments, they’re my go to.
This is really nice kit. All merino is nice to wear but it can be fragile and look like outdoor kit. Thought has been given to nice looks and gussets so it doesn't tear at the seams. Comfortable, smart and warm. What's not to like.
My new black long sleeve polo style shirt is really lovely. Great looking, good fit, and very warm. Hopefully as it's merino it will keep it's look for a long time to come too.

Mens Merino 200 Long Sleeve Polo Shirt (Black/Blue)
The product is as expected and washes well.
Nice bold colour, slimmish fit around the middle if needed some wriggle room
Great quality and very good fit.
Mens Merino 200 Long Sleeve Polo Shirt (Petrol/Lime)
Absolutely love it. So comfortable and perfect fit. Postage surprisingly cheap to Aus .
Das Poloshirt hat eine schöne Farbe zum Kombinieren mit einer Jeans. Da ich sehr viele Shirts von Isobaa habe, weiß ich, dass die Shirts für meinen Mann, der eine breite Schulter hat und normalerweise Größe XL trägt, immer in XXL passen, wobei sie dann etwas kürzer sein dürften. Doch die Qualität ist langlebig und Pflege einfach.
Very nice quality - I bought it for bikepacking but it a nice piece of kit to wear causally.
I have been wearing the merino 200 long sleeve for a little over a year now mostly for active wear. They run small. I am 6'2 with a slim build and ordered a large but still found it a little too short in the arms and torso, so size up. I have also just found a hole in the bottom of the shirt which is a little disappointing and makes me question overall durability. Having said that I have just ordered two more in an XL so I must be somewhat satisfied!
Thanks for the review and for ordering again!
We’re sorry to hear about the hole — our products are covered by a 2-year warranty, so please don’t hesitate to reach out to our support team if you’d like us to take a look. For the best long-term performance, we also recommend following our care guide.

The Isobaa Team
I love the look and comfort of the shirts but I've had several now where the fabric developed a hole or tear through normal wear.
Thanks for your feedback, Robert — we're glad you love the look and comfort of the shirts.
Merino can be a naturally delicate fabric, but holes from normal wear definitely aren’t expected. Please do get in touch with our support team with images of the faults, and we’ll be happy to help make it right.
Smart casual layering
Good material, close fit, nice long sleeves, would prefer if there where more one colour options rather then the coloured collars. Only criticism is that the threads on the sleeve have started to unravel so am monitoring to see if I need to send it back
Ordered medium last time a little small now large a little large
I have several of these, good comfortable jerseys. Good length in torso and arms. Sizing seems to be getting smaller so consider going up a size. I'll be getting XL for next ones.
Easy to wear and warm. Feels good when wearing it
