90% cotton, 10% recycled polyester

These shorts will age beautifully: thanks to the heathered fabric, the color resists UV rays well and stains are barely noticeable. The sage color, on the other hand, will fade slightly with each wash (as with all cotton clothing).
They may lose their shape a bit over the years (though less so than a 100% cotton version), except at the waistband, thanks to the elastic band.

Tie a knot in the drawstrings before putting it in the washing machine; otherwise, they might get lost inside the waistband.

It’s 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 it will extend the garment’s lifespan. Also, 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., the delicate or synthetic cycle) so it doesn’t lose its elasticity. The best way to extend its lifespan and be kind to 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 amount of shrinkage after the first wash. Don't worry—this is normal, and the fabric will stabilize after that.

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 fleece shorts therefore have an environmental cost of 942 impact points*.

By comparison, a garment of equivalent weight, made of 100% polyester, manufactured in Bangladesh, and sold by a fast-fashion brand, has an environmental cost of 2,719 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 polyester, particularly because it requires few pesticides (and thus poses a low toxicity risk to freshwater) and is biodegradable (and thus causes fewer issues with 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.
