Natural vs. Synthetic

There’s a common myth that natural fibres are better for the environment because they are natural. But as with most things in life, it’s not that simple. Every fibre impacts the environment, whether it’s natural or synthetic. For example, conventional cotton needs a lot of water, wool uses a lot of land and traditional synthetics are made from fossil fuels. And all of them shed microfibres that persist in the environment, not just synthetics as widely believed.

Just like when you’re devising a recipe, you need to find a balance. Each fibre has its own qualities and for every piece of clothing we design at H&M Group, we make conscious decisions about which fibres we use based on environmental impact, durability, functionality, fit and recyclability. Because to be sustainable, clothing needs to be used more, last longer and not be thrown away.

Jeans – the ultimate wardrobe staple  

To explain, let’s start with a pair of jeans. These stalwarts of fashion have stood the test of time to become a wardrobe staple. Boyfriend, skinny, mom – there’s a fit and a style for everyone. Originally designed as workwear for miners, they were made of cotton because of its durability.

The problem is that pure cotton fabric is stiff. There’s no give and it can be scratchy against the skin. Imagine trying to pull on a pair of skinnies that don’t stretch. Adding just a couple of percent of elastane softens up the denim making it much more comfortable to put on and wear.

Socks – the wardrobe workhorse

Now let’s take a look at socks. If you live in a cold climate, you probably have a drawer full. We’ve got pairs for every occasion – sports, winter, work, non-slip, slipper and lots, lots more. Socks not only keep our feet at the right temperature but also cushion and protect our skin.

Single fibre socks like wool or cotton can be good for temperature regulation, but they wear quickly. Before long, your toes are peeking out one end and your heel the other. Combining natural fibres with a little synthetic makes a longer-lasting sock, leaving your feet fresh and covered up.

Sportswear – the functional wardrobe

Our final example is exercise clothing. Early sportswear was made from wool or cotton but when natural fibres get wet, they stay wet. And when you’re pounding the streets heading for a PB the last thing you want is cold fabric clinging to your body.

Synthetics outperform natural fibres for sportswear every time. Their unique qualities mean they wick away moisture so your sweat evaporates back into the air and you can concentrate on hitting that time.

Using a fibre mix

We need a mix of natural and synthetic fibres to create clothes that last and that people want to wear again and again. Because it’s not in the least bit sustainable if your socks get holes after three weeks or your jeans never get worn because they’re too tight around your middle.
