Look and feel of the products are great although the sizing needs a review. I fit comfortably into XL for Rab and North Face but Isobaa is XXL and even that in one T-shirt is too tight. Delivery... See more

Fantastic product
I bought a hiking shirt and am so pleased with it. I wore it on several hot days of hiking and it just didn't smell! It also sits well and true to size. Would 100% buy again.

Still smelling fine after 400 sweaty miles
I've just walked 400 miles in Spain in a mix of hot windy and wet conditions and the top has fared well. Fabric has suffered a bit where it was in contact with my rucksack and a button for a sleeve strap fell off despite the strap never being used. These though are points of detail.

Thanks for sharing such a detailed review. We’re really pleased to hear the top kept you comfortable across so many miles.
The fabric is reinforced at the shoulders to support pack wear, though we’ll certainly take your feedback on the button and durability on board. We appreciate you putting it through its paces and helping us improve, and we've issued you a partial refund as a gesture of goodwill.

Great quality merino clothes
The only thing I wish for is slimmer versions, especially of bottoms and all the base layers (vest, T-shirt, long-sleeve). Currently, men's S is too wide for me, but the length is perfect.

Super light insulated merino jacket

Speedy delivery and great products. Merino isn't an easy fabric to get right, and Isobaa have put in some really effective touches. Great for indoor and outdoor fun.

Great in every way only wish they had light colours as the tshirts can get hot with lots of sun.

Thank you for your review!
We’re really glad you’re enjoying your products. We don’t usually produce lighter colours in our lighter weight Merino, as the fabric can be a little see-through, but we’ll keep your feedback in mind for future ranges.

Received 4 shirts as a gift
Received 4 shirts as a gift, 3 got major holes after s couple of months. Needed order number for them to do anything which I don't have. Bad products, bad company

Thank you for your review. We’re very sorry to hear about your shirts.
Our products are designed to be durable, so holes developing after only a few months is unusual and something we take seriously. In some cases this can be linked to how the garments are cared for, which is why we always recommend following the care instructions closely.
Our warranty applies to the original owner and requires proof of purchase so that we can trace the product and provide the right support. If the gift-giver is able to share the order details with you, our customer service team will be glad to review this further.

The worst experience with T-shirts I ever had. All T-shirts have holes after 3 months. The first shirt after the first washing with
just 30°C. Terrible. Don't buy Isobaa shirts. You'll 100% regret it.

A bit thin in the nether regions!
You asked me to write a review for winter base layers, which I had bought at the end of the winter when they were offered at a very advantageous price. I can’t therefore offer a sensible review until halfway through next winter because I haven’t worn them yet although from earlier use of similar items for cycling id say that they wear out too quickly in the bit where the saddle supports my bum.
Having read your reply, it’s worth mentioning that I wear them as a base layer, with winter cycling tights including a chamois pad for comfort. Wearing them as an outer (or only) layer wouldn’t make sense.

Reply from Isobaa Merino
Thanks for taking the time to write a review.
We’ll keep your point about saddle wear in mind, though the tights are designed as a base layer rather than for direct saddle contact. We’d be keen to hear how they hold up once you’ve put them to use next winter.
[UPDATE]
Thank you for clarifying! If you do experience premature wear & tear, please get in touch with our support team—they'll be happy to assist. You may find the thicker 260gsm version offers greater durability with regards to friction exposure.

Isobaa Gets It Right
Good service, great products. Lovely soft, comfortable Merino clothing with nice sizing. Comfortable out of the box and wears well for several days even while being active. Washes well and dries quickly, great for travelling.
