The wool overshirt
€145 isn't cheap. But a good wool flannel comes at a price. And the details are well thought out: an inside pocket, a lining in the sleeves so you can wear it over a t-shirt, thick buttons sewn on in a cross… And finally, it's the price of production close to home in Europe, where the workers are paid a decent wage.
Released in December 2024
To keep you warm without overheating (that's right, wool breathes).
Thanks to the fineness of the wool fibres and the fulling (meaning the fabric has been rubbed with hot water to make it felt).
This overshirt is made in Portugal, at the Marfel factory we've worked with since 2023.
Worn, tested and approved by thousands of customers, this shirt is the result of several years of continuous improvement. We've refined it over time to reach a quality-ethics-price balance that we now consider optimal.
For example, we could lower the price by using a less soft, less dense fabric or one with less wool, but the overshirt would be less warm and less pleasant to wear.
The techniques behind the quality
Thick fabric
The fabric's high density (320g/m2) helps delay the appearance of holes (especially at the elbows) and keeps you nice and warm
Thick fabric
Fulling
Thick buttons
Fulling
A process that consists of lightly felting a wool cloth — in other words, compacting it by applying moist heat and mechanical movements. The wool fibres intertwine, forming a dense, warm, naturally water-repellent and also very soft material.

Thick buttons
Thick buttons
We went for thick resin buttons that won't break in the wash, unlike wooden or mother-of-pearl ones.
Just in case, a spare button is sewn onto the composition label.

Staying warm in any season
Wear it like a jacket over a t-shirt, or under a coat in winter. Thanks to its thick, soft wool cloth, this shirt will keep you warm all year round.
In detail
Woollen melton
It's the name of this slightly felted, downy fabric.
Deep shade
The fabric is made of wool fibres in slightly different colours: that's what gives the colour its depth.
Two exterior pockets
It's practical and it's good-looking.
An inside pocket
So you can wear this overshirt as a jacket.
Lined sleeves
With an organic cotton fabric, so it can be worn over a t-shirt without scratching and slides on easily when you put it on.
How to wear it
A few ideas if you're stuck
Composition
100% virgin wool
Origin and certifications
- Wool: Portugal and Uruguay
- Spinning and dyeing: Portugal and India
- Weaving and manufacturing: Portugal
... make it in Portugal and not in France? Of course, producing in Portugal lets us sell at a lower price. But it's also easier to achieve good quality there: in the 1980s, when France offshored its industry, Portugal strengthened its own. That said, others manage to make wool overshirts that are 100% made in France, like AATISE.
How this product will age
How do we know? We ask our customers what they think of the product one year after they've bought it. And if the product is less than a year old, we give you our predictions based on some spontaneous feedback and on our experience with similar products.
This overshirt won't lose its shape at all, thanks to the elastic properties of wool. It might end up pilling slightly, for example on the sides from your elbows rubbing... but nothing a fabric shaver can't handle. The biggest risk is moths, if they settle into your wardrobe – here's an article we wrote to help you get rid of them.
Care instructions
No washing machine, to avoid any shrinkage: if you really want to wash this overshirt, do it by hand or take it to a dry cleaner. A word of caution: in that case, be sure to ask for "dry cleaning" (and not water-based "wet cleaning", which some dry cleaners use and which can cause slight shrinkage).
But you probably won't need to go that far: on wool, stains usually come off with a good dab of a damp sponge (without rubbing too hard, so you don't pill the area). And besides, wool is antibacterial: it doesn't hold on to odours if you air it out regularly.
Environmental cost
This environmental cost is calculated using the official methodology of the French environmental labelling scheme (in force since 1 October 2025).
The label above shows the product's environmental cost according to the official methodology of the French environmental labelling scheme. It's what its manufacture "costs" nature when you look at its impact on climate change, ocean acidification, its toxicity for freshwater, and so on. Currently rolled out in the textile sector, this label should soon appear on many everyday consumer products (food, cosmetics, furniture, etc.) to help you shop in a more responsible way.
The wool overshirt therefore has an environmental cost of 3373 impact points*.
By comparison, a garment of equivalent weight, 100% acrylic, made in Bangladesh and sold by a fast fashion brand, has an environmental cost of 3629 points*.
Why the difference? Here are the main reasons:
- The countries of production: manufacturing in Portugal or France requires less fossil fuel than in Bangladesh (one of the main producers of low-cost clothing). The result: this more local manufacturing limits the impacts on climate change, ocean acidification and resource depletion.
- The material: wool has a fairly significant environmental impact, in particular because sheep release methane when they digest, a gas with a strong greenhouse effect. That's why the difference between the impact of our product and that of fast fashion isn't very large. However, unlike acrylic, wool has major advantages: it's warm (thanks to its insulating properties), keeps its shape (the fibre is very elastic), breathable (it wicks away perspiration) and odour-resistant (it prevents bacteria from developing).
- Durability: fast fashion brands encourage you to buy, in particular by refreshing their collections very quickly and offering a huge number of items, and they discourage repairs by charging ridiculously low prices. This increases the number of garments sold per person and reduces the number of times a garment is worn. At Loom, we've done the opposite: we've chosen business practices that encourage our customers to keep their clothes as long as possible.
Even though we've done everything we can to keep it as low as possible, the environmental impact of this product is not negligible. So before you buy, make your clothes last as long as you can.

Reviews for this product
The standard practice is to send review request e-mails a few days after the purchase. We wait a month, the minimum time needed to form a well-informed opinion
Customer review policy
When do you ask customers for reviews?
We send you a review request one month after you receive your order. We reckon that's the minimum amount of time needed to have worn and washed a garment several times and to really form a well-informed opinion. After that, all your reviews are published within the week, whether they're good or not.
Do you ask for reviews on 100% of the products customers order?
We used to do that at first, then we realised we were starting to send far too many emails to some people who buy from us regularly. In short, we were spamming a bit. On top of that, it was starting to take up way too much of the team's time to reply to reviews - since we want to reply individually and privately to almost every person who leaves us a review. Today, we no longer ask for reviews on products that meet the following two criteria: 1/ There are enough reviews shown on the site for people who want to buy to form a well-informed opinion about the product 2/ We've read enough reviews within the Loom team to understand how to improve the product for the next generation.
Hold your horses: what proves we don't tamper with reviews by slapping 5 stars everywhere?
Honestly: nothing, we're just giving you our word. Same as for everything else, by the way: where we manufacture, where our wool comes from, our lab test scores, and so on. The only times we might touch what you write are if your message contains spelling mistakes (and even then, quite a few slip past us) or if it's racist, homophobic, and so on (but that's never happened so far).
Asking for a review after a month isn't enough to know whether the clothes really are durable, is it?
You're right, which is why we send you another review request email a year after your purchase – we even ask for a photo to see how your garment has aged. The answers help us improve our clothes and provide information about "how this product will age" on our product pages. To avoid bothering our customers needlessly, we don't ask for these reviews on 100% of the products ordered: as soon as we have enough data to understand the areas for improvement, we stop asking for the one-year reviews.
