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 wear 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 make a run for it :)
- Metal eyelets replaced with embroidered ones (no risk of them peeling off)
These joggers are made mostly from organic cotton, meaning cotton grown using organic farming methods (we explain that choice here), plus a bit of recycled polyester for durability.
A sweatshirt-style fabric, a bit heavier than average
These joggers are made in Portugal, at the Triwool factory we've worked with since we started out in 2017.
The techniques that ensure quality
Polyester reinforcement
We added a recycled polyester thread to the fabric to limit stretching (residual deformation after one minute of 6.7 mm vs. 7.8 mm for 100% cotton) and double the abrasion resistance (holding up to 50,000 cycles vs. just 25,000 with 100% cotton).
Heads up: just because polyester is recycled doesn't mean it'll solve all the environmental problems of the textile industry... more info here.

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

Pre-washing
These joggers are pre-shrunk 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 staying power
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
Since these joggers are made from a fairly stretchy fabric, the back pocket had a tendency to gape and your wallet a tendency 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 drawstring glide through without damaging the fabric. Unlike metal eyelets, there's no risk of them coming loose.
How to wear it
A few ideas if you're stuck
Composition
90% cotton, 10% polyester
Origin and certifications
- Knitting, dyeing and making-up: Portugal
- Cotton and spinning (solid colour): Indonesia
- Marled colour:
- Cotton: Sudan, India, Turkey
- Spinning: Turkey
... 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: 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. While a few die-hard Gauls manage to grow it 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 shape, and it'll never pill.
You might notice a slight sag at the knees by the end of the day — but that vanishes after a wash.
The black will fade a little with washing (just like every cotton garment out there).
If you wear it hard for sport, it may develop holes in the friction zones (the crotch) faster than a 100% polyester jogger would.
Care instructions
It's machine-washable at 40 degrees, but it's better to wash it at 30°C: just as effective, far greener, and it'll make it last longer. Then, whatever you do, wash it inside out to avoid any fading or risk of pilling.
You can put it in the tumble dryer (it happens...) but if you do, use a low temperature (i.e. the delicate or synthetic setting) 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. Don't worry, it's normal and it will settle down afterwards. If you find the joggers loosening 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 France's 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 being rolled out in the textile sector, this label should soon appear on many everyday consumer products (food, cosmetics, furniture, and more) to help you shop in a more eco-responsible way.
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:
- Where things are made: 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 production limits the impacts 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 because it's biodegradable (so fewer issues with microfibres or end-of-life waste).
- Longevity: fast fashion brands push people to buy, largely by refreshing their collections at breakneck speed and offering huge numbers of styles, and they discourage repairs by charging laughably low prices. This drives up the number of garments sold per person and cuts down the number of times each garment gets 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, this product's environmental impact isn't negligible. So before buying, make your clothes last as long as you possibly 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
Politique d'avis client
Quand demandez-vous des avis aux clients ?
On vous envoie une demande d’avis un mois après la réception de votre commande. On estime que c’est le minimum de temps nécessaire pour avoir porté et lavé un vêtement plusieurs fois et se faire vraiment un avis éclairé. Ensuite, tous vos avis sont publiés dans la semaine, qu’ils soient bons ou non.
Est-ce que vous demandez des avis sur 100% des produits commandés par les clients ?
On le faisait au début, puis on s’est rendus compte qu’on commençait à envoyer beaucoup trop d’emails à certaines personnes qui achètent régulièrement chez nous. Bref, on spammait un peu. En plus, ça commençait à nous prendre vraiment beaucoup trop de temps dans l’équipe de répondre aux avis - puisqu'on veut répondre individuellement en privé à presque chaque personne qui nous laisse un avis. Aujourd’hui, on ne demande plus d’avis sur les produits qui répondent aux deux critères suivants : 1/ Il y a suffisamment d’avis affichés sur le site pour que les personnes qui souhaitent acheter puissent se faire une opinion éclairée sur le produit 2/ Nous avons lu dans l’équipe Loom suffisamment d’avis pour comprendre comment faire évoluer le produit à la prochaine génération.
Minute papillon : qu’est-ce qui prouve qu’on ne modifie pas les avis en mettant des 5 étoiles partout ?
Honnêtement : rien, on vous donne juste notre parole. Comme pour le reste d’ailleurs : où on fabrique, d’où vient notre laine, la note de nos tests labos, etc. Les seules fois où on pourrait toucher à ce que vous écrivez, c’est si votre message contient des fautes d’orthographe (et encore y en a pas mal qui nous échappent) ou s’il est à caractère raciste, homophobe, etc (mais ça n’est jamais arrivé pour l’instant).
Demander un avis au bout d’un mois, ce n’est pas assez pour savoir si les vêtements sont vraiment durables, non ?
Vous avez raison, c’est pour ça qu'on vous envoie un autre e-mail de demande d'avis un an après votre achat – on demande même une photo pour voir comment votre vêtement a vieilli. Les réponses nous servent à améliorer nos vêtements et à donner des informations sur "comment ce produit va vieillir" dans nos pages produits. Pour ne pas solliciter inutilement nos clients et nos clientes, on ne demande pas ces avis sur 100% des produits commandés : dès que nous avons suffisamment de données pour comprendre les points d’amélioration, nous arrêtons demander les avis à un an.
