The joggers
Released in January 2020
Released in January 2021
- Switched to GOTS-certified organic cotton
- Added 10% recycled polyester so it sags less at the knees and takes longer to develop holes at the crotch
- Longer, redesigned cut so it's less tight around the calves
- Added a zip to the back pocket so your wallet doesn't do a runner :)
- Metal eyelets replaced with embroidered eyelets (no risk of them peeling off)
These joggers are made mostly of organic cotton, meaning cotton grown using organic farming methods (we explain that choice here), and a little recycled polyester, for durability.
Full composition: main fabric 90% organic cotton, 10% recycled polyester; ribbing (waistband and leg hem) 98% organic cotton, 2% elastane.
A sweatshirt-type fabric, a bit denser than average.
These joggers are made in Portugal, in the Triwool factory we've been working with since we started out in 2017.
The techniques behind the quality
Polyester reinforcement
We added a recycled polyester thread to the fabric to limit sagging (residual deformation after one minute of 6.7 mm vs. 7.8 mm for 100% cotton) and double the abrasion resistance (resistance of 50,000 cycles vs. only 25,000 with 100% cotton).
Careful: just because polyester is recycled doesn't mean it'll solve all of textiles' environmental problems... more info here.

Elastane reinforcement
Before we figured out how to make ankle ribbing that doesn't lose its stretch, we spent nearly €1,000 on lab tests. And bingo, we found the right structure: the elastane needs to be knitted "in jersey" – diagram at this link if you're into the technical side.

Pre-washed
These joggers 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).

Cotton with a bit of structure
Cotton joggers are comfy, but they tend to lose their shape over time. To limit the problem, we chose a dense organic cotton fabric, with 10% polyester so they won't bag at the knees. Bonus: a zipped back pocket for your keys or credit card.
In detail
French Terry
On the inside, small flat loops that soak up sweat.
Zipped back pocket
Because the joggers are made from a fairly soft fabric, the back pocket had a tendency to gape open, giving your wallet the perfect excuse to make a run for it. So we added a YKK zip to keep everything where it belongs.
Adjustable belt
The waistband is elasticated and lined with a drawstring.
Embroidered eyelets
They let the drawcord slide through without damaging the fabric. And unlike metal eyelets, there's no risk of them coming loose.

... make 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: back in the 80s, when France offshored its industry, Portugal strengthened its own. That said, others besides us manage to make excellent joggers that are 100% made in France, like La Gentle Factory.
... does cotton come from so far away? Cotton always comes from far away. Although a few die-hard Gauls manage to grow some in their fields, cotton farming is marginal in Europe.
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 jogger will stay in good condition, without ever pilling.
You may notice slight sagging at the knees by the end of the day — which disappears after washing.
The black colour will become less deep with washing (as with all cotton garments).
If used intensively for sports, it may develop holes in the friction areas (crotch) faster than a 100% polyester jogger.
Care instructions
It's machine washable at 40 degrees, but it's better to wash it at 30°C: it's just as effective, far greener and it'll extend its lifespan. Then, always wash it inside out to avoid fading and any risk of pilling.
You can tumble dry it (it happens...) but if you do, use a low temperature (i.e. delicate or synthetic mode) so it doesn't lose its stretch. The best thing for its lifespan and for the planet is to dry it flat, on a drying rack or a towel.
Of course, it's cotton, not kevlar: despite our best efforts, there may be a very slight shrinkage after the first wash. No worries, that's normal and it'll settle down afterwards. If you find the joggers loosen up a bit, a quick spin in the machine should tighten the knit back up and restore its original feel.
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 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 joggers therefore have an environmental cost of 1321 impact points*.
By comparison, a garment of equivalent weight, made of 100% conventional cotton, manufactured in Bangladesh and sold by a fast fashion brand, has an environmental cost of 5714 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 fabric: organic cotton has a fairly low environmental impact compared to conventional cotton, notably because it uses few pesticides (so low toxicity for freshwater) and because it's biodegradable (so fewer issues with microfibres or end-of-life waste).
- Durability: fast fashion brands drive purchases in particular by renewing their collections very quickly and offering a huge number of styles, 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, on the other hand, 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 you can.

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