As we explore new ways to make our activewear more sustainable, a good starting point is ensuring what we already own is cared for properly.
Merino wool is one key piece of kit that can have its life significantly extended with a little care.
A key fabric for sport and fitness, merino wool has become a hugely popular fabric in recent years, and that’s because of its unique ability to be both warm yet breathable.
It makes merino perfect for wearing while exercising or exploring the outdoors and it’s a property that’s hard to find, even in many synthetic fabrics.
The drawback is that caring for a wool can be difficult. But with, our guide, you’ll find that keeping your merino wool products in performance-ready condition is easier than you might think.
What is merino wool?
Merino is a breed of Spanish mountain sheep with wool that, apart from being naturally biodegradable (obviously), is highly thermo-regulating and capable of wicking moisture away from the skin. It’s also naturally odour resistant, supremely soft, and protective against damaging UV light.
How to wash merino wool
Luckily, merino wool is machine washable but stay clear of hot water and heat as these can shrink your garment. It’s best to opt for a gentle cycle in warm or cool water.
To keep each piece working at its best for longer, you should use mild or regular detergent and avoid softeners or bleach as these destroy the natural merino wool fibres.
Hand washing should also be avoided as it can cause a residual soap build-up in the garment that can lead to odour issues. Plus, separating your light and dark washes as you would normally limits colour fading.
How to dry merino wool
Stuffing your merino in a hot tumble drier is not a good idea if you want it to stick around. Whether it is your favourite hat, base layer, or gloves, the best way to keep each piece in top condition is to dry them on the line or lay them out flat.
You can, however, tumble dry your socks if you turn them inside-out and use on a low heat setting.
Merino wool is good at bouncing back into shape after washing so ironing isn’t always necessary but, if needed, it’s best to iron inside-out and on a cool or wool-specific setting.
Adding a thin layer between the iron and garment, such as a pillowcase, will also save any potential burning or harm to the delicate fibres.
Storing your merino wool
It is always best to clean your merino wool pieces before storing as this will prevent odour, stains, and dirt build-up.
For optimum results, storing each item folded rather than hung will reduce loss of shape.
And, if you need to pack away garments for long periods of time - such as between seasons - then sealed garment bags or containers will be your best friend in protecting the merino wool from moths and insects.
For more detailed instructions, please read your garment’s care label.
