100% wool

Thanks to the elastic properties of wool, this sweater will barely lose its shape. If the sleeves stretch out a little, you can tighten them back up with an iron as explained here. This sweater will also hold up well at the elbows thanks to the thickness of the fabric – so far, only a small handful of people have reported a hole to us.
It might occasionally pill slightly in areas of friction, on the sides for example... but nothing a fabric shaver can't handle (and the more pills you remove, the less likely they are to come back).
The biggest risk with this wool sweater is moths, if they settle into your wardrobe! So here's a short article to read here to keep them from moving in.

No need to wash this sweater: airing it out for 24 hours will get rid of any smells. But if you really want to, you can put it in the machine (wool cycle).

No tumble dryer, to avoid any risk of shrinking the sweater. Don't dry it on a hanger either: your damp sweater is heavy and could stretch out of shape under the weight of the water. For its lifespan (and for the planet), the best option is to dry it flat, on a drying rack or a towel.

That said, you're absolutely free to iron it — quite the opposite! It can even help it get back into shape.

By the way, if the edges of your sweater lose their shape, we explain here how to tighten them up with your iron.

The label above shows the product's environmental cost according to the official methodology of the French environmental labelling scheme. It reflects 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 thick sweater (old generation) therefore has an environmental cost of 2765 impact points*.

By comparison, a garment of equivalent weight, 100% acrylic, made in Bangladesh and sold by a fast fashion brand has an environmental cost of 3233 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 production limits the impact on climate change, ocean acidification and resource depletion.
• The material: wool has a fairly significant environmental impact, partly because sheep release methane when they digest, a gas with a strong greenhouse effect. That's why the difference between our product's impact and that of fast fashion isn't very large. That said, unlike acrylic, wool has major advantages: it's warm (thanks to its insulating properties), keeps its shape (the fibre is very elastic), breathable (it wicks away sweat) and odour-resistant (it stops bacteria from developing).
• Durability: fast fashion brands drive purchases by, among other things, refreshing their collections extremely quickly and offering a huge number of styles, 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 to keep it as low as possible, this product's environmental impact is far from negligible. So before you buy, make your clothes last as long as you possibly can.
