The joggers
Released in January 2020
Released in January 2021
- Switch to GOTS-certified organic cotton
- Added 10% recycled polyester to reduce stretching at the knees and delay the formation of holes in the crotch
- Elongated cut, redesigned to be less tight around the calves
- We've added a zipper to the back pocket so your wallet doesn't make a run for it :)
- Metal eyelets replaced with embroidered eyelets (which won't come loose)
These sweatpants are made mostly of organic cotton—that is, cotton grown using organic farming methods (we explain this choice here)—and a small amount of recycled polyester for durability.
A sweatshirt-like fabric, slightly thicker than average
These sweatpants are made in Portugal at the Triwool factory, with which we have been working since our inception in 2017.
Techniques That Ensure Quality
Polyester reinforcement
We’ve added a recycled polyester thread to the fabric to reduce creep (residual deformation after one minute: 6.7 mm vs. 7.8 mm for 100% cotton) and double its abrasion resistance (50,000 cycles vs. only 25,000 for 100% cotton).
Note: Just because the polyester is recycled doesn’t mean it will solve all the environmental problems associated with textiles... more info here.

Pre-wash
Spandex reinforcement
Before we figured out how to make ribbed cuffs that don’t stretch out, we spent nearly €1,000 on lab tests. And bingo—we found the right structure: you have to knit the spandex “in stockinette stitch”—check out the diagram at this link if you’re interested in the technique.

Pre-wash
These sweatpants are pre-shrunk and stabilized at the factory to prevent them from shrinking at home (with cotton clothing, most of the shrinking occurs during the first wash).

Cotton and Style
Cotton joggers are comfortable, but they tend to lose their shape over time. To minimize this problem, we chose a dense organic cotton fabric with 10% polyester to prevent them from losing their shape at the knees. Bonus: a zippered back pocket for your keys or credit card.
In detail
French Terry
On the inside, there are small, flat loops that absorb sweat.
Back pocket with a zipper
Since the joggers are made of a fairly stretchy fabric, the back pocket might have gaped open and your wallet could have slipped out. So we added a YKK zipper to give you peace of mind.
Adjustable belt
The waistband is elastic and has a drawstring.
Embroidered eyelets
They allow the cord to slide through without damaging the fabric. Unlike metal grommets, 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 garment manufacturing: Portugal
- Cotton and Spinning (Solid Color): Indonesia
- Mottled color:
- Cotton: Sudan, India, Turkey
- Spinning: Turkey
...manufacture in Portugal instead of France? Of course, manufacturing in Portugal allows us to sell at lower prices. But it’s also easier to produce high-quality products there: in the 1980s, when France moved its manufacturing overseas, Portugal strengthened its own manufacturing sector. That said, other companies besides ours manage to make very good sweatpants that are 100% made in France, such asLa Gentle Factory.
... does cotton come from so far away? Cotton always comes from far away.While a few die-hard Gaulsmanage to grow it in their fields, cotton farming is a niche activity in Europe.
How This Product Will Age
How do we know this? We ask our customers for their feedback on the product one year after purchase. And if the product is less than a year old, we provide our predictions based on some unsolicited feedback and our experience with similar products.
The joggers will stay in good condition and will never pill.
You may notice a slight loosening at the knees by the end of the day—which disappears after washing.
The black color will fade slightly with washing (as with all cotton clothing).
If used intensively for sports, it may develop holes in areas subject to friction (such as the crotch) more quickly than 100% polyester sweatpants.
Care Instructions
It’s machine-washable at 40 degrees, but it’s better to wash it at 30°C: it’s just as effective, much more eco-friendly, and it will extend the garment’s lifespan. Be sure to wash it inside out to prevent discoloration and pilling.
You can put it in the dryer (it happens…), but if you do, use a low temperature (i.e., delicate or synthetic cycle) so it doesn’t lose its elasticity.The best way to ensure its longevity and to help 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—this is normal and will stabilize afterward. If you find that the joggers stretch out a bit, a quick spin in the washing machine should tighten the fabric and restore its original feel.
Environmental Cost
This environmental cost is calculated using the official methodology of the French environmental labeling system (to be rolled out starting October 1, 2025).
The label above shows the product’s environmental cost according to the official French environmental labeling methodology. This represents what its production “costs” nature when considering its impact on climate change, ocean acidification, its toxicity to freshwater, and so on. Currently in use in the textile sector, this label should soon appear on many everyday consumer products (food, cosmetics, furniture, etc.) to help you make more eco-friendly purchasing decisions.
Jogging therefore has an environmental cost of 1,321 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 5,714 points*.
Why is there this difference? Here are the main reasons:
- Countries of origin: Manufacturing in Portugal or France requires less fossil fuel energy than in Bangladesh (one of the leading producers of low-cost clothing). As a result, this more local manufacturing reduces the impacts on climate change, ocean acidification, and resource depletion.
- The material: Organic cotton has a relatively low environmental impact compared to conventional cotton, particularly because it uses few pesticides (and thus poses a low risk of toxicity to freshwater) and is biodegradable (and thus causes fewer issues related to microfibers or end-of-life waste).
- Sustainability: Fast-fashion retailers encourage purchasing—in particular by rapidly refreshing their collections and offering a vast number of styles—and they discourage repairs by charging rock-bottom prices. This, in turn, increases the number of garments sold per person and reduces the number of times a garment is worn. In contrast, at Loom, we’ve chosen to adopt business practices that encourage our customers to keep their clothes for as long as possible.
Even though we've done everything we can to minimize it, this product's environmental impact is not insignificant. So before you buy, make sure to get the most use out of your clothes.

Please note: The number of points is not always exactly the same on Ecobalyse (whose methodology changes regularly) as on the official environmental label (based on Ecobalyse version 7.0).
Reviews of this product
The standard practice is to send review request emails a few days after the purchase. We wait a month—the minimum amount of time needed to form an informed opinion.
Customer Review Policy
When do you ask customers for reviews?
We’ll send you a review request one month after we receive your order. We believe this is the minimum amount of time needed to have worn and washed an item several times and to form a truly informed opinion. After that, all your reviews are published within a week, whether they’re positive or negative.
Do you request reviews for 100% of the products ordered by customers?
We used to do that at first, but then we realized we were starting to send way too many emails to certain customers who shop with us regularly. In short, we were spamming them a bit. Plus, it was starting to take the team way too much time to respond to reviews—since we want to reply individually and privately to almost everyone 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 posted on the site for potential buyers to form an informed opinion about the product. 2/ We on the Loom team have read enough reviews to understand how to evolve the product into the next generation.
Just a quick thought: What proof is there that we aren't manipulating reviews by giving 5-star ratings to everything?
Honestly: nothing—we’re just giving you our word. Just like with everything else, actually: where we manufacture our products, where our wool comes from, our lab test results, and so on. The only times we might edit what you write is if your message contains spelling mistakes (and even then, quite a few slip past us) or if it’s racist, homophobic, etc. (but that’s never happened so far).
Asking for feedback after just one month isn't enough to know if the clothes are really durable, is it?
You're right—that's why we send you another email asking for a review one year after your purchase—we even ask for a photo to see how your garment has aged. We use the responses to improve our clothing and to provide information on “how this product will age” on our product pages. To avoid unnecessarily bothering our customers, we don’t ask for reviews on 100% of the products ordered: as soon as we have enough data to understand where we can improve, we stop asking for reviews after one year.
