These thermal bottoms are seconds quality. There may be a slight imperfection in the sewing but this will not impact on your ability to wear and enjoy the product. They are unbagged and unpressed, so may look a little disheveled on arrival. Strictly no change-of-mind or size returns on these


Our new Unisex Merino Thermal Bottoms are made from a stretchy Australian merino and elastane blend. Weighing in at 200gsm, these thermal leggings are ideal for most chilly conditions you're likely to be presented with in Australia and New Zealand. 

Ethically made in Australia, our merino thermal bottoms incorporate a beautifully soft Ottie Merino-branded waistband, and a couple of external sewns pockets—so you don't get that annoying pocket bunch-up against your legs—because pants without pockets suck! At 200gsm, we're talkin' a great 'allrounder' thermal bottom. 

Paired with a men's or women's merino thermal top, these merino thermals pants are a must for the well-prepared and cool weather hiker or skier. 

- Australian merino and elastane blend—the best of ALL worlds in terms of performance, comfort, and durability (95% merino, 5% elastane)
- Pockets to keep them hands warm, or for handily stowing your phone, headlamp, or matches at camp or the hut
- Available in small to xx/large (see size chart)
- 100% mulesing-free 
- Sweatshop-free! 
- Made in Melbourne
Australian Made certified
- All the benefits of merino wool—odour resistant, moisture wicking, temperature regulating, super soft, biodegradable, and comfortable AF!
- Designed by hikers, for hikers (and and skiers and snowboarders and people who get cold!) 

You may notice a bit of colour variation from the pics here. See colour swatch to get a better idea for the colour. We'll be getting some better product photography real soon. Including an awesome snowy winter shoot.

Stitching Coming Undone

Nice fabric. But stitching was coming undone on pockets of pants just weeks after purchase. Had similar problem with the cuff of long-sleeved top. Disappointed. I was expecting much better quality.

Very comfortable and warm - good style for leggings. Liked the pockets!
The measurement guide made it much easier to pick the right size. And I will use for more than hiking

So far so good!

They arrived today! Slipped them on and they felt like high quality. Much thicker than my macpac thermals and they come with pockets. The cut was a little strange and different to my other branded pairs but I'm thinking they will shape to my body as they age. I will recommend these!

Merino Thermals FAQs

In thermals, you need stretch. This is so they sit nice and close to the skin and provide the best insulative qualities. Pure merino is stretchy but not quite enough. Our Australian merino/elastane blend gives you softness, stretchiness, as well as all the benefits of merino.

Why not?

You don't know you're missing a pocket until you need one. You're at Clinton Hut on the Milford Track or at a campsite on the Larapinta Track. Just in your thermal clobber—we hikers/trampers are all about high-fashion, after all—and you've nowhere to pop your headlamp or phone or pack of matches. Nice for warming the hands too.

Same as with t-shirts. 30 days. No fuss. We're happy to do size and change of mind exchanges or credits or refunds. They just need to come back to us in pristine, resellable condition. Email support@ottie.com.au before returning any items though so we can walk you through the process.

Oh, and with the bottoms, make sure you try them on with your undies on.

If you place an order now and choose to cancel the order before the thermals arrive that's perfectly fine. A credit or exchange or full refund is available - your choice.

Ah, the logistics of manufacturing clothing.

The charcoal marle these will be produced in are a 'custom colour' with our manufacturer. We sampled in black as we developed the product. So we had to get a bit creative in Photoshop for the initial product photos, just until we get out batch of photography samples and we do a full photoshoot. Hopefully in Kosciuszko National Park which'll be a stunning backdrop!

Around 35gsm in weight for a start. Our lightweight 100% merino tee is 165gsm and our thermals are 200gsm. Perfect for cooler conditions. And, our thermals are a merino/elastane blend, which lends itself a bit better to 'baselayer' wear.


Not only are we Australian Made certified, we're Ethical Clothing Australia accredited.
