The boxer briefs will stay in great shape, stretch out very little and won't develop holes any time soon (only a small handful of customers have reported holes after several years of wear).
That said, like all cotton garments, it will lose a little of its softness and shine over time as you wash it.

It's machine washable at 40 degrees, but it's better to wash it at 30: it's just as effective, far greener, and it will extend its lifespan.
And above all, inside out, to better protect the colours. 

For its longevity and for the sake of the environment, the ideal is to air-dry it. But sometimes you don't have a choice: if you have to use a tumble dryer, do it on low heat (i.e. on the delicate or synthetic setting) to keep it from losing its elasticity and damaging the fibres too much.

Lastly, it may feel a bit snug around the thighs at first: that's normal, and it stops it from riding up too much over the course of the day. It will loosen slightly the more you wear it.

If it pills a little against the skin the first few times you wear it, that's normal: the pills will disappear completely after a few washes.

If it looks a bit shiny at first, that's normal too: this slightly silky appearance comes from the fineness of the cotton fibres, which give it its softness and strength. But don't worry, this shine tends to fade wash after wash.

The label above shows the product's environmental cost according to the official methodology of the French environmental labelling scheme. It's what its manufacturing "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, etc.) to help you shop more responsibly.

The boxer briefs therefore have an environmental cost of 263 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 943 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 manufacturing limits the impact on climate change, ocean acidification and resource depletion.
• The material: organic cotton has a fairly low environmental impact compared to conventional cotton, notably because it uses few pesticides (so low toxicity for freshwater) and is biodegradable (so fewer issues with micro-fibres or end-of-life waste).
• Durability: fast fashion brands drive purchases by refreshing their collections very 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 taken the opposite path: we've chosen business practices that encourage our customers to keep their clothes for as long as possible.

Even though we've done everything to keep it as low as possible, the environmental impact of this product isn't negligible. So before buying, make your clothes last as long as you can.
