Why Are Merino Wool Thermals So Good?

If you’ve ever wondered ‘are Merino wool thermals good?’, then this blog was made for you. We’re going to unravel why they’re an absolute game-changer. From performance benefits to their sustainable footprint, there’s so many reasons to invest in Merino wool thermals.


High-Tech Benefits of a Merino Wool Base Layer

For a natural fibre, there are a surprisingly large number of benefit that make Merino wool thermals so good. From moisture-wicking capabilities and thermogenic properties, to odour, stain and wrinkle-resistance, there’s not much this A+ fibre can’t do.



1. Superior Insulation

Thermals made from Merino wool offer next-level warmth without the bulk. Despite their lightweight feel, this particular fibre loves to trap in body heat, to keep you warm in the chilliest conditions. 


2. Moisture-wicking 

Working up a sweat? Merino wool has your back. Remarkably, this fibre has moisture-wicking properties which means it helps to pull sweat away from your skin no matter how high your heart rate gets. Whether you're lapping chairlifts or hiking rugged trails, Merino wool’s moisture management prowess will help you stay fresh and dry all day long.


3. Thermoregulating

Unlike synthetic materials, Merino wool is like your body's personal air con, always adjusting to keep you feeling just right - it’s what we call “thermoregulating”.

When things heat up, it works its magic by whisking heat away from your skin, making you feel up to twice as cool compared to synthetics. But when it’s cold, it will help to trap heat close to your body to keep you toasty warm. So, whether you're sweating it out in the summer sun or heading out into the snow, Merino wool has got your back, keeping you comfortable no matter what the temp.


4. Odour-Resistant

Unlike polyester, Merino wool thermals have natural anti-bacterial properties that keep odour-causing bacteria at bay. Perfect for those post adventure drinks at the bar or campfire hangs.


5. Stain and Wrinkle-Resistant

Ever spilled your morning coffee on your favourite shirt? Not a problem for Merino wool. Its fibres come with a built-in shield that says “nope” to stains. Plus, it’s not a fan of static so it doesn’t attract as much dust or lint. What’s more, each tiny Merino wool fibre is like a spring that bounces back into its original shape after bending. For the average person, that means no wrinkles making it the perfect low-fuss travel companion.



Low-impact and Sustainable Benefits of Merino Wool Thermal Underwear

We’ve said it once and we’ll say it again, Merino wool is the ultimate high-tech, low-impact fibre. Its sustainable benefits are tough to match being 100% natural, renewable and biodegradable. It’s what makes Merino wool thermals the ultimate active wardrobe must-have.


Merino Wool is 100% Natural

Coming straight from the back of happy and healthy Merino sheep, Merino wool is as natural as it gets. No funky chemicals or artificial additives here, just Mother Nature’s finest fibres to wrap you up in warmth and softness.


Merino Wool is 100% Renewable

Harvested from our fluffy friends, the Merino sheep, this wool grows back year after year, ensuring a constant and sustainable supply so you can go ahead and cozy up in your merino wool thermals guilt-free, knowing you're supporting renewable practices.


Merino Wool is 100% biodegradable

Returns can be sent back into the ground since Merino wool is 100% biodegradable. Unlike its synthetic counterparts that can stick around for centuries, Merino wool naturally breaks down over time. So, when your trusty merino wool thermals finally reach the end of their journey, rest easy knowing they’ll leave nothing behind.

We all know that in Australia, we have to deal with so many diverse landscapes. From sun-kissed beaches to snow capped mountains, our gear needs to adapt to ever-changing conditions. That’s where Merino wool thermals take the win.

Better yet, here at XTM Performance we opt for Woolmark Certified Australian Merino wool. That means you're getting the cream of the woolly crop when it comes to sustainable farming practices. It also means you're supporting our Aussie wool growers, all 60,000 of them.
