100% cotton

This sweater will age very well: unlike a wool version, it won’t shrink in the washing machine, pill, or develop holes at the elbows.
However, like all cotton garments, it may lose its shape slightly over the years. Despite the spandex thread we’ve added to the sleeves, they may stretch out if you pull them up over your big biceps.
We’ve chosen a durable knit stitch, but the textured structure still carries a slight risk of snagging (fortunately, this is easy to fix).

This sweater is machine-washable at 40 degrees, but it’s best to wash it at 30°C: it’s just as effective, much more eco-friendly, and will extend its lifespan (especially color retention).

Be careful—the cotton may eventually stretch out if you pull on it too much: keep in mind that if you wear the sleeves rolled up, this can eventually cause the sleeves to stretch out a bit.

Do not tumble dry, as this may cause the sweater to shrink. Don’t dry it on a hanger either: your damp sweater is heavy and could lose its shape under the weight of the water. The best way to ensure its longevity and be kind to the planet is to dry it flat on a drying rack or a towel.

However, you’re definitely allowed to iron it—in fact, you should! It can even help it regain its shape after a machine wash.

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.

The textured sweater therefore has an environmental cost of 1,324 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 4,701 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.
