The Tencel tank top
Released in May 2022
This is still the first generation of this tank top, because there's nothing obvious to improve.
After plenty of trials with 100% cotton, we finally went for a fabric made mostly of Tencel. It drapes beautifully, it doesn't cling to the skin and it feels wonderfully soft. The other advantage is that it doesn't wrinkle and gives you a flawless look… even if you've just rolled out of bed.
Composition: 64% Tencel, 32% cotton, 4% elastane.
A slightly higher-than-average density to prevent transparency and limit stretching.
A shape that follows the body's line without clinging to it.
If you prefer a more fitted cut, take a look at our ribbed vest top.
This tank top is made in Portugal, at the Triwool factory we've been working with since we started out in 2017.
Worn, tested and approved by thousands of customers, this tank top is the result of a quality-ethics-price balance that we now consider optimal.
For instance, we could make the white less see-through by increasing the thickness, but it would become too heavy and lose its shape more over time.
The techniques behind the quality
Tencel–cotton blend
Tencel for softness, drape and wrinkle-free properties, and cotton (GOTS-certified organic) for structure.

Elastane reinforcement
Pre-washed
Elastane reinforcement
To prevent your socks from stretching out of shape over the years (residual deformation 3 times lower than the same knit without elastane).

Pre-washed
This tank top is stabilised and pre-washed at the factory so it won't shrink on you (with garments that contain cotton, most of the shrinkage happens during the first wash).

Light and flowing
Tencel (a fibre made from wood pulp) for a cool feel and a lovely drape, (organic) cotton for structure, and an elastane yarn to keep it from stretching out over the years: three ingredients that give our tank top a beautiful, comfortable and durable fabric. As for the cut, we took our first customers' feedback into account to develop a shape that's close to the body without being tight. So you don't have to sacrifice anything – neither comfort nor style.

Origin and certifications
- Spinning, knitting, dyeing and making-up: Portugal
- Lyocell: Austria
- Cotton: Tanzania
... 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: back in the 80s, when France offshored its industry, Portugal strengthened its own. That said, others manage to make excellent tank tops that are 100% made in France, like 1083 or Le Slip Français.
... the cotton comes from so far away? In reality, cotton always comes from far away: while a few die-hard holdouts manage to grow it in their fields, cotton farming is marginal in Europe. For this tank top, the yarn is bought directly by our knitter, and it isn't possible to choose the origin of the cotton.
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 tank top will stay in great condition and stretch out very little. We've only been selling it for under a year, but so far no signs of ageing have been reported to us.
Care instructions
It's machine-washable at 40 degrees, but it's better to wash it at 30: just as effective, far greener and it'll extend its lifespan. Then, wash it inside out no matter what to avoid fading and any risk of pilling.
For its longevity and for the good of the environment, the ideal is to line-dry it in the open air. But sometimes you don't have a choice: if you have to use a tumble dryer, do it on low heat (i.e. delicate or synthetic mode) to keep the elastane from losing its stretch and to avoid damaging the fibres too much.
Of course, this tank top isn't made of kevlar: despite all our efforts, there may be slight shrinkage on the first wash. No need to worry, it's normal and it'll settle down afterwards.
To keep the white version from turning grey or yellow over time, wash it well away from your other clothes. And if you want to freshen up the white now and then, just follow this recipe (very simple, we promise).
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 fresh water, and so on. Now 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 more responsibly.
The Tencel tank top therefore has an environmental cost of 300 impact points*.
By comparison, an equivalent-weight garment, 100% viscose, made in Bangladesh and sold by a fast fashion brand, has an environmental cost of 856 points*.
Why the difference? Here are the main reasons:
- The production countries: 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 impact on climate change, ocean acidification and resource depletion.
- The material: Tencel is more environmentally friendly than viscose, the material usually used by fast fashion for this type of drape. Both materials are made from wood pulp, but Tencel is made with non-toxic solvents in factories running an almost closed-loop system.
- Durability: fast fashion brands drive purchases in particular by refreshing their collections very quickly and offering a huge number of items, and they discourage repairs by charging laughably 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, this product's environmental impact isn't negligible. So before buying, 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.
