Isobaa Merino Reviews 

The company kept me informed throughout the purchasing and delivery experience and used Royal Mail as a courier which is very reliable. The quality of the products are excellent having previously purchased similar items I have not been disappointed with the products purchased in this order.

Great quality.

I have had this jumper for about 2 months now and I absolutely love it. It is warm and soft with good length and sleeve length, and a beautiful colour. I have worn it a lot!

After a hiccup during the delivery the customer support helped with no hesitation and a very smooth handling of the issue. In the end I had to wait a little longer but that’s alright. The product itself is amazing, fits well and does what the company advertises. :) 5*

I have bought Isobaa from Sportpursuit and direct from isobaa. Regarding the clothing, I haven't kept anything yet because the sizing is so inconsistent. But my main beef is returning goods to Isobaa for a refund. They just stopped communicating even though I could see the returns parcel had been delivered. They stated it took 14 days for the warehouse to process packages which seems to take no account of regulations stating that the customer must be refunded within 14 days. In the end I raised a dispute with my credit card company and got my money back that way. Once I raised the dispute, I did hear from them again but by that tine it was out of my hands. Would never buy from them again. It wasn't until I'd ordered from SportPursuit that I realised they're the same company and they've had my returns for 3 days now with no acknowledgement of receipt. I wouldn't have so many returns if the sizing was in any way predictable

Accurate sizing
Remarkably comfortable and not overheating with activity
The only issue was the washing instruction tags inside the waistband which would have made these boxers unwearable. I have removed the tags (4 labels thick) but given the otherwise outstanding quality I cannot understand this oversight.

Not worn yet. But if they are like my previous Isobaa purchases, they will be very comfortable, feel good and look good.

Love Isobaa clothing! Always great quality and always delivered in minimal packaging and on time.

Quality of the garment even though I haven't worn it yet

2 stars — Good clothing generally, but Merino 180 boxers have all failed

I am generally a fan of Isobaa clothing. I own several hoodies, T-shirts and other items, with total purchases over £400, and much of it has become my regular clothing.

However, the Men’s Merino 180 Boxers have been very disappointing.

I bought four pairs through SportPursuit across two orders in May 2025 and October 2025. All four have now worn through in essentially the same place across the seat. Three had already failed by June, including both October 2025 pairs in under nine months. The remaining Forest/Denim pair has now failed in the same way.

These boxers were part of a rotation of around ten pairs, so they were not being worn constantly. All Isobaa garments were washed according to the care instructions, and we wash them separately from ordinary laundry to protect the merino fabric and avoid abrasion from other garments.

I contacted Isobaa about this in June but received no response. That is frustrating, especially because this looks like a repeated durability issue rather than a one-off damaged garment.

I understand that merino can be more delicate than synthetic underwear, but all four pairs of the same product failing in the same area is not acceptable durability at this price point.

I am giving 2 stars rather than 1 because I do like Isobaa clothing generally, and I would still like to give the company the chance to resolve this properly. I will update this review if they respond and offer a fair remedy.

Nice warm layers but you do need to be skilled at darning, every jersey I've had has developed a hole or two. Or the cuff shreads, not a repair I can make.

I've used Isobaa for many years now and rate their products very highly.
All the clothing is extremely well tailored and comfortable as a result.
All items are extremely hard wearing while also being very soft to the skin.
I have never had any of my purchases ripe or tear and they have all kept their shape and size even after many washes.
Excellent products from a very reliable firm.

Great joggers and can't wait for winter to enjoy their warmth.

All my branded stuff is going in the bin. I’ll only be buying my activewear from Isobaa from now on. Can also be used as loungewear because it’s so comfortable.

And the puns are funny 😄

I order a lot from this company for good reason. The quality is superb, consistant and reliable. The service is prompt and polite when there are queries, and the sizing is perfect for me. I tend to wait for the sales then order for myself and for gifts for friends/family, who also enjoy countryside adventures on and off the bike.

I've bought two Isobaa products but have been dissatisfied with both. The first - a long sleeve t-shirt 100% wool - is so itchy that I've chosen to not wear it on hikes. I've had other brands of merino before, like Icebreaker and Decathlon, and not encountered this problem, so it's definitely to do with the fabric they use.
The second product was a merino sports cardigan, and this developed a hole after a just a couple of uses and washes.
Although I like the cuts and look of their garment, I feel I have little choice but to conclude that the quality of materials they use is lacking, or else I have been extremely unlucky.

Wore isobaa 3 different models while hiking in the Dolomites kept me ultra comfortable managing moisture

Delivered quickly and looks excellent quality,too hot to wear just now,but wouldn't hesitate to use this company again

Love the products, service and company principles

Quality products and easy ordering. Like all merino wool products they are expensive. But affordable in the sale times.
