1. 100% Australian Merino = All Season Comfort
Our Woolmark Blend®, Responsible Wool Standard (RWS) Certified merino wool is 100% biodegradable, naturally thermoregulating and easy to care for — making it our favourite fibre, baaaaa none. And ready for whatever nature throws your way.

2. Moisture wicking + odour resistant
Merino wool wicks away sweat and stays breathable even in warm climates or when you’ve been hoofing it. So it’s odour free, night and day. And because it’s grown in diverse Australian conditions, it’s also the perfect fibre for adventuring in changeable weather.

3. The sweet spot between warmth & lightness
Our lightweight 170g rib fabric is made from 18.5 micron fibres, delivering year-round temperature control in warm and cool climates. And our Merino Base Layers roll up into not much at all, so they’ll squeeze into your backpack for every adventure.

4. You’re wrapped in nature
Immersed in nature’s wilds, there’s no better feeling than being wrapped in 100% natural Australian fibres. Hike, run, jump, frolic and feel connected to your surrounds — in all conditions — with woolly abandon.

5. Umm… Have you seen my..?
It’s your underlayer, only layer, pyjama, running shirt, just-in-case, stash-for-anything, go-to, grab-and-go that you can never find anywhere… Because it’s so comfortable you forgot you were already wearing it.

FAQs
What's the fabric composition of the Merino Base Layers?
Our lightweight, 100% Australian 170g rib merino is made from 18.5 micron fibres, delivering year-round temperature control in warm and cool climates.
Will it feel scratchy or itchy against my skin?
Nope. Our merino fabrics are super-soft and designed to be worn next to your skin, where they help regulate your core temperature year-round.
How warm is it, and is it good for humid or mild climates?
Our Merino Base Layers can be worn as an underlayer beneath jackets, jumpers and fleeces in cold environments, and also work as a lightweight single layer in mild weather. Naturally odour resistant, merino wicks away sweat, so is a great option in warmer climates and high humidity.
"I wore this shirt for the entire 48km Kokoda Challenge, including through hours of rain. I was pleasantly surprised how I was neither cold or hot and didn’t smell terrible after such a long hike!" - Laura B

Merino Base Layers: Layers of love from merino devotees.
We took inspo from Australia’s 80-million sheep and created natural Merino Base Layers for nature-lovers.
Our favourite fibre, baaaa none
We’ve always loved merino fabrics. They help maintain a stable core temperature. They stay odour-free, even after sweaty exertion. And, as the old adage says, wet wool’s warm! So it’s the perfect fibre for outdoors time in changeable weather. What we love most about our Merino Base Layers, is that feeling of being wrapped in 100% natural Australian wool, and how that connects us more closely to our natural surrounds. Deep in the mountains or by the coast, as we walk, run, sweat, sleep, wake up and walk again, Merino wool is always, always, always our first choice.
100% natural wool fabrics made by Australia
Another thing we know about merino is that done wrong, things can get itchy. So in developing our Merino Base Layers we worked hard with our partners to hit that sweet spot of year-round warmth and lightness: which we now know is 170g rib fabric, made from 18.5 micron fibres. We also worked hard to ensure the environmental credentials of our suppliers, and we’re proud that all our merino products meet the Certified Woolmark Blend®, and Responsible Wool Standard (RWS) Certified standard. Since launching in 2023, our Australian Merino Wool Base Layers have quickly grown to become one of our best overall categories. And as devotees of merino ourselves (even in our sub-tropical Queensland surrounds), we know it’s just as much about the all-weather functionality as it is about our eye-catching colourways.
