Fabric weight: 180gsm
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.

Offset shoulder seams
Shoulder seams are shifted away from the top of the shoulder, so rucksack straps sit comfortably without rubbing or causing irritation on longer days out
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
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.

Ordered an XL based on size chart for someone who normally wears an S or M. It did fit as specified width-wise, but was extremely long, almost tunic-like--which was anticipated based on the sizing. It's a good look, though, if you like tunics. Feels very slim-fit-Italian, like AX or other similar brands. The shipping was surprisingly slow but the fabric feel was almost comparable to cotton. Really liked how light and versatile the top ended up being. There were some minor issues with seams but customer service was responsive and offered to replace to make it right. Was glad there were no interior tags and the printed info did not show through to the outside, either, so nice touches there!
Thank you for the detailed review.
We're glad you appreciate the design and feel of the top, and that our customer service met your expectations. We are sorry for our slower shipping times across the pond, but we hope the products were worth the wait.
If there's anything more we can do for you, please let us know.
Kind regards,
The Isobaa Team
I really like this top. It hits a good balance between light, warm and coping when the weather is changeable. Nice and packable.
Dear ISOBAA, I'd love a full zip version without a hood, maybe a bit heavier weight and ideally with at least one zip pocket, for a smarter warm layer when travelling. It's so hard to find full zip non-hoodies.
Thank you for the feedback! We'll share your suggestion with our design team. :-)
This is a great quality top - well made and looks good. It is good either on its own, or as an extra insulating layer in the winter for outdor activites. I am 5'4" tall, slim build, narrow shoulders and small bust. The small size is perfect, would fit someone 3 inches taller in terms of body and arm length and accommodate women with wider shoulders and bust.
Absolutely love the colours of this top - I wear merino long sleeve tops and T shirts all the time as fashion tops as well as for when I am hiking in the mountains and skiing. They are soft and comfortable and do not have that scratchy itchy feel that you get with some merino items 😊
Great fit, really cosy for windy sailing. Love the feel.
Great quality
Fantastic striped top. Fits perfectly,love it.
I bought the grey woolly T-shirt to add a bit of variety, as I already own three black ones. The material is lovely, and I couldn’t be happier with it.
I love my woolly T-shirt. The stripes on the sleeves add a fun touch, and the quality of the material is excellent. It washes really well too. I can’t recommend it enough.
Womens Merino 180 Long Sleeve Crew (Stripe Charcoal/Smoke)
I love everything about this top. Good stripes, nice neckline, sleeves long enough, cosy without being hot.
Excellent. Perfect fit. Great colour. Warm
I’m 162cm/49kg I use this for night wear.
It’s so comfortable and easy to move.
Have wanted a merino top for hiking, for a long time and am really glad I bought this one. It fits well, it’s smooth to the touch, so really nice to wear. It keeps me warm when I need to be, but I don’t get over hot when the temperatures rise. A great base layer that looks good too.
I am really pleased with my recent purchase of the Merino 180 long sleeve crew top. It is a good fit, and comfortable to wear. It kept me lovely and warm whilst walking in the Lake District in the recent cold and wet weather.
Bien taillée et agréable à porter. Testée hier en randonnée, c'était très agréable
Really good length and body shape.
Bought 5 merino base layers in the sale. Excellent fit, excellent quality.
Comfy to wear
I’d been looking for a cosy base layer for a while but wanted something more funky than the plain purple or teal which seems the norm for women. The stripes are gorgeous and little subtle branding.
Loved the packaging on arrival too
Well made garments, perfect for these cool days without bulk.
I'm so pleased l made the purchase.
Womens Merino 180 Long Sleeve Crew (Navy/Wine)
I had been looking for long sleeved merino tops that weren't just black. I really feel the cold and layers of natural fabrics (silk and wool) are the perfect solution. I am a recent fan of merino tops as they are snug, but lightweight. This is the 2nd I have bought, this one was reduced in the sale so I couldnt resist. I know I will wear them a lot, especially useful for travels with the added bonus that wool doesnt need washing so often. The sleeves are a little long and so is the length but I don't find this gets in the way as they don't hang loose. The length means it can't pop out of my trouser wasitband either, which keeps me warm.
Great fit, colour and comfort.
