The slim jeans
We sell these jeans for €100. Yes, it's not cheap… but it's not that expensive either:
- Our fabric (_made in Italy _and organic cotton) costs almost twice as much as made in Asia denim made from conventional cotton: our ethics and our quality choices come at a cost.
- And the making is careful and _made in Portuga_l, so with wages far higher than 95% of the jeans on the market — which mostly come from Asia or North Africa.
But since we don't do collections, sales, or ads, and our shareholders don't push us to make a big margin (more details here), we sell it for "only" 100 euros.

Released in September 2024
- Blue colour: the indigo dye is better fixed, fades less quickly and bleeds less
Released in April 2025
- Blue: now in a fabric that stretches out less
- Black: now in a more comfortable, more durable fabric
We use organic cotton because so-called "conventional" cotton is a disaster for insects, birds and farmers (more info in this article) and a little elastane for comfort.
Composition: 98% organic cotton, 2% elastane.
Fitted without being tight, the semi-slim cut follows the line of the leg (it's the equivalent of the Levi's 511 cut). If you're looking for a cut with more room, take a look at our straight-leg jeans.
These jeans are made in Portugal, at the 5D factory, which we've worked with since 2019.
Worn, tested and approved by thousands of customers, these jeans are the result of several years of continuous improvement. We've refined them over time to reach a quality-ethics-price balance that we now consider optimal. For example, we could make them more hard-wearing by adding polyester, but that would have a negative impact on the environment, on comfort or on odour retention.
The techniques behind the quality
Stay black
The black colour is achieved with a so-called "reactive" dye, which won't fade over the washes. Note: this isn't the case for the blue colour, which uses a classic indigo pigment dye that will develop a patina over the washes.
Stay black
Dense fabric
Low-abrasion fabric
Pre-washed
Dense fabric
A density of around 350g/m2 for the black version and around 490g/m2 for the blue versions: that's the right compromise to last over time while staying wearable all year round.

Low-abrasion fabric
Pre-washed
Low-abrasion fabric
Fairly soft, low-friction fabric to delay the holes that form at the crotch from thigh-against-thigh rubbing (see this article for more details). Fabric-against-fabric abrasion resistance over 100,000 cycles.

These jeans are stabilised and pre-washed at the factory, so they won't shrink at home (with cotton clothing, most of the shrinkage happens during the first wash).

The classic
Jeans made from organic cotton, with a slim cut that follows the line of your leg, and a touch of elastane for comfort. The fabric is dense but supple enough to keep you comfortable, and not too rough, so holes take longer to appear. The deep blue will fade beautifully over time and the black will stay black. In short, these jeans should age just as gracefully as you (okay, maybe not QUITE as gracefully, but you get the idea).
In detail
A blue that patinas over time
The blue fabric comes from Candiani, an Italian maker of quality denim. It's dyed with indigo, a dye that will fade with friction and washing.
A black that stays black
The black fabric has been dyed with what are known as "reactive" dyes so it won't fade over time.
Deep, sturdy pockets
26 cm tall to fit your hands, and a 120 g/m2 fabric to withstand your keys.
Semi-automatic YKK zip
A zip developed by the leading Japanese brand, which stops your fly from opening on its own: when the pull tab is folded down, the slider is completely locked. As soon as you lift the tab, the zip unlocks and the fly can be opened or closed.

98% cotton, 2% elastane

... make them 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 besides us do manage to make very good jeans that are 100% made in France, like 1083.
... a fabric that comes from Italy and not from France? On our first productions, the fabric came from the Vosges, in eastern France. Unfortunately, in France the minimum order quantities were too high and the production lead times too long for it to be viable for us. In a difficult period for ethical brands, and with our cash flow being limited, we opted for an Italian denim (from a renowned weaver: Candiani).
... the cotton comes from so far away? Actually, it's hard to get any closer. While a few die-hard Gauls manage to grow it in their fields, cotton farming is marginal in Europe. The closest places where we can source it are Egypt, Turkey and Greece.
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.
The colour of these jeans will develop a patina over time. Like most jeans, they'll stretch out a little as you wear them (about half a size) and tighten back up a bit after washing.
If holes start to appear after a while, take these jeans to an alterations and repair shop right away: the professionals there can fix them for around twenty euros.
To all the cycling, motorcycling, horse-riding fans, or anyone else who travels by straddling something: these jeans are tough, but not indestructible. If your steed tends to wear holes in your jeans, take a look at the brand Bolidster instead.
Care instructions
Read before trying on:
If your jeans feel a little tight at the waist and thighs on the first try-on, that's fairly normal: they'll stretch out slightly after a few hours of wear.
The leg length is fairly generous: if you find them too long, you can roll up your trousers or have them hemmed by your favourite tailor.
Careful, the raw version of the denim can leave blue marks on your hands or on light-coloured clothes. Why? We explain it in this article. So for the first 5 washes, avoid wearing it over your brand-new white underwear, your spotless light-coloured shoes, or your beige sofas.
Read before washing:
To avoid discolouration marks on your jeans (like the streaks caused by rubbing on the folds in the washing machine), it's important to wash them inside out, at 30°C, and not to overload the machine. And to keep them from coming out too creased and make ironing easier: spin at a low speed (600 rpm max) and hang them up while still damp.
If you really want to put it in the tumble dryer, choose the delicate or synthetic setting to avoid any risk: your jeans contain a little elastane that could stretch out at high temperatures.
Don't iron it too hot: the elastane (yes, it again) could melt at too high a temperature. And to avoid any shiny marks, iron it inside out.
If after a few years you start to notice wear at the crotch, take it to your tailor quickly before a real hole appears and it's too late.
And don't forget to empty your pockets before putting it in the machine :)
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 manufacturing "costs" nature when you look at its impact on climate change, ocean acidification, its toxicity to 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 more responsibly.
The slim jeans therefore have an environmental cost of 1457 impact points*.
By comparison, a garment of equivalent weight, made from 100% conventional cotton, manufactured in Bangladesh and sold by a fast fashion brand, has an environmental cost of 5516 points*.
Why this 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 impact on climate change, ocean acidification and resource depletion.
- The material: organic cotton has a fairly low environmental impact compared to conventional cotton, notably because it uses few pesticides (so low toxicity for freshwater) and it's biodegradable (so fewer issues with microfibres or end-of-life waste).
- Durability: fast fashion brands drive purchases in particular by refreshing their collections very quickly and offering a huge number of styles, and they discourage repairs by charging absurdly low prices. This increases the number of garments sold per person and reduces the number of times a garment is worn. At Loom, by contrast, 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, this product's environmental impact isn't negligible. So before you buy, make your clothes last as long as possible.

Please note: the number of points isn't always exactly the same on Ecobalyse (whose method evolves regularly) as on the official environmental labelling (based on version 7.0 of Ecobalyse)
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.
