The boxers will stay in great shape, barely stretch out, and won't get holes anytime soon (only a tiny handful of customers have told us about 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 30 is better: just as effective, far greener, and it'll make your garment last longer.
And ideally inside out, to better preserve the colours. 

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

Finally, it might feel a bit snug around the thighs at first: that's normal, and it keeps the garment from riding up too much over the course of the day. It'll loosen up slightly the more you wear it.

If it pills a little against your skin the first few times you wear it, that's normal: it'll 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 durability. But no need to worry — that shine tends to fade wash after wash.

The label above shows the environmental cost of the product according to the official methodology of the French environmental labelling scheme. This is what its manufacturing “costs” nature when you look at its impact on climate change, ocean acidification, its toxicity for freshwater, etc. Currently rolled out in the textile sector, this label should soon appear on many everyday consumer products (food, cosmetics, furniture...) to help you buy in a more eco-responsible way.

The boxer shorts therefore have an environmental cost of 263 impact points*.

By comparison, a garment of equivalent weight, 100% conventional cotton, made in Bangladesh and sold by a fast fashion brand, has an environmental cost of 943 points*.

Why this difference? Here are the main reasons:

• The producing countries: manufacturing in Portugal or France requires less fossil energy than in Bangladesh (one of the main producing countries for low-cost clothing). Result: this more local manufacturing limits the impacts on climate change, ocean acidification or resource depletion.
• The material: organic cotton has a fairly low environmental impact compared to conventional cotton, notably because it uses few pesticides (hence low toxicity for freshwater) and because it is biodegradable (hence fewer issues with microfibres or end-of-life waste).
• Durability: fast fashion brands encourage purchasing, in particular by renewing their collections very quickly and offering a very large number of references, and they discourage repairing by charging derisory prices. This therefore increases the number of garments sold per person and reduces the number of times a garment is worn. Conversely, at Loom, we have chosen business practices that encourage our customers to keep their clothes for as long as possible.

Even though we did everything to make it as low as possible, the environmental impact of this product is not negligible. So before buying, make your clothes last as long as possible.
