Mens Merino Wool Insulated Jacket (Navy/Orange)
Using the latest 'FulFil' Merino insulation technology from UK based HD Wool, this baffled jacket offers amazing warmth and protection using insulation that's made from recovered wool fibres collected during yarn production, so nothing goes to waste. Unlike feather & down, Merino will still insulate even when wet, so you can stop worrying about the weather forecast. Merino will keep you warm when it's cold and breathes well when it's warm, keeping you comfortable whatever the weather. It's also quick drying, naturally odour resistant and sustainable.
Our jacket outer fabric is made from recycled GREENLON® Nylon - wasted yarn from the textile industry is manufactured into recycled chips, which then go through spinning process to produce nylon recycled yarn. This outer fabric is then treated with a Durable Water Repellent coating (C0 DWR / PFC free) to give you further protection from the elements.

It’s a poor construction with many areas of the jacket having zero filling. Rain water runs directly through to you inner garments in less that 3 min.
Thank you for taking the time to share your feedback, Philip. We sincerely apologise for any inconvenience you experienced with our jacket.
We want to clarify that the jacket is treated with a DWR (Durable Water Repellent) coating, which makes it water-resistant but not fully waterproof. It is designed to withstand light rain and moisture, but prolonged exposure or heavy rainfall may lead to water penetration.
We regret to hear that you found areas of the jacket lacking filling. This is not the standard we aim to uphold, and we appreciate you bringing this to our attention. The baffled stitching pattern is designed to keep the insulation well-filled and evenly distributed throughout the jacket. The purpose of these baffles is to prevent the merino insulation from shifting or clumping together, ensuring that the jacket retains its warmth and loftiness. Based on your description of areas with 'zero filling', it sounds as though you may have received a faulty product.
Your satisfaction is our priority. Please reach out to our support team, who will assist you in finding the most suitable resolution.
Once again, we apologise for any disappointment caused and thank you for your honest feedback. Your input helps us improve our products and services to better meet the needs of our customers.
Kind regards,
The Isobaa Team
This is a well made jacket and the material is windproof. I had already purchased a ladies version but wanted one a bit larger so I can easily fit a fleece under in winter so I purchased a man’s size and it was ideal. It is very comfortable to wear and looks smart as well. I would recommend this as a good buy.
This has become my new "daily driver". I've quickly become a big fan of Isobaa.
Just got back from a cold week in the mountains and as using this for the first time. Has held up well as a layer for under the wind /rain outer . Light and easy to stash . No loft , so unlike a down jacket it can be easily layered , which I did and needed it as it was freezing. Packs small enough to disappear when not on.
After feedback on here the return was promptly processed and is all re credited to my account
This is a relief as the products from this company are superb
This is my first jacket but I have 4 of the merino wool layer tops which are superb for golf and will be visiting The Alps in January
Will be buying more in the New year ….. good luck in ‘ 26 ISOBAA
Sorry to hear about this. That’s not the experience we want to provide. We’ll look into the return and make sure the refund is resolved as quickly as possible.
Really good jacket - have been looking for an ethical option for ages and just spotted this in sale. Looks great and keeps me lovely & warm.
This jacket seems perfect at first glance. It's warm, sure. But it's definitely not odor-resistant. I wore it one day skiing and couldn't wear it again for the whole week because it smelled so bad. And if I have to pay €15-20 every time I wear it for dry cleaning, it's not worth it. Too bad, I liked it at first.
Thanks for your review and for giving the jacket a try. We're sorry it didn’t meet your expectations for odour resistance.
We appreciate your feedback and will share it with our design team — they're already exploring machine-washable options.
Please get in touch if you have any questions or need assistance.

Unfortunately it's coming from the Far East not to say China, but decently crafted, and at 70% of a boosted price, it's fair enough as wool last longer than down. Still an unknown enough compagny not to be overwhelmingly cheap like most big brands of so-called outdoor gear turned to seve the "urban lifestyle", looking confortable at trees, high mountains, high waves on the sea, infinite deserts, wild rivers and so forth of true adventure territories facing their screen in the warmth of ...wool !
Love this jacket, very versatile and best of it’s kind.
Decided to buy a jersey and few other things after being turned on to Isobaa from a recommendation via a bike-packing YouTuber.
Really good quality clothing that wicks away moisture and smells fresh even after a few hours of strenuous exercise.
Bought more stuff whilst their sale was on and this too was brilliant....just took a while to get here, but was defo worth the wait.
The jacket is light and very warm - ideal for wearing as an outer or mid-layer. Highly recommended.
Thank you for your fantastic feedback, Scott! We're so glad to hear you’re enjoying the jacket and we appreciate your recommendation.

Nice feel; denser than down, but still light. Hopefully better in wet conditions than down! Comfortable outer material. Looks good.
Thanks for the great feedback, Ben!
We’re glad to hear you’re enjoying the jacket! We can assure you it'll outperform down in wet conditions — the merino insulation will keep you warm even when damp.

A nice light weight jacket which is great for the unpredictable English weather. It is warm enough if you are out and about but I found it to light to wear on a winters day watching your kids playing sport.
Really impressed with this. Warm and fits well. Only issue is that it’s dry clean only, when the hoodies I’ve bought here can be washed in my machine.
We appreciate the review, Stu!
Glad you're enjoying the warmth and fit of the jacket, and we totally get your point about machine washability. We're working towards more machine-washable options for future iterations.
Kind regards,
The Isobaa Team
Despite being a hillwalker/ backpacker/ climber for nearly 50 years, this is the first time I have succumbed to the temptation of an insulated jacket! It has fully lived up to expectation so far in some freezing temperatures. Really looking forward to trying it on some trips. Great design and good fit.
Thank you for the review, Rod!
We're delighted to hear that our jacket has impressed someone as adventurous as yourself! It's wonderful that it has met your expectations in the cold and we're excited for you to take it on many more trips.
Kind regards,
The Isobaa Team
I bought this jacket after owning down and synthetic for many years. What an amazing jacket!! Keeps me warm in all conditions, especially in downpours it holds it own and I feel comfy and warm. Only negative is that it needs dry cleaning and changes colour around the neck on the hood. Other than that which is nothing really, this is the best I’ve worn and is my go to for everything!
Thank you for your glowing review, Mark.
We're delighted to hear that this has become your go-to jacket. You may be pleased to hear that we're in the early stages of exploring an alternative design that won't be restricted to dry-clean only.
Please feel free to get in touch if you ever have any questions or concerns.
Kind regards,

Super comfy and great fit. Will be buying more!
Mens Merino Wool Insulated Jacket (Petrol/Lime)
Second purchase extending the experience. Now trying the heavier merino long sleeve, hoodie long sleeve and puff jacket. Hard to regret joining the flock.
This is one of various items in my first orders from Isobaa and I continue to be highly impressed. The jacket is high quality, great zip, great warmth. The hood is perfect - it has good overhang so it'll keep out the cold and the rain. The pockets are good and deep, and, interesting, are fashioned so that they are partly detached from the inside lining. There are drawstring toggles on the waist, and friction tape draw ribbon on the hood. I would have preferred slightly longer sleeves, because my arms are quite long.
Really happy with the jacket, it looks great, fits true to size and is really comfortable. The jacket also came wonderfully packaged in a very nice box.
I loved the jacket the moment I opened the package. The red colour is wow and the feel is quality.
The size is a little more generous than I expected but still good. If you are wavering between sizes my experience suggests the smaller one.
