Our new Women's Merino Thermal Top is made from a stretchy Australian merino and elastane blend. Weighing in at 200gsm, this thermal t-shirt is designed to be your go-to base layer whether you're hiking the Milford Track in NZ in early spring or skiing Buller in August. 

Ethically made in Australia, this merino wool thermal top sports raglan sleeves so you don't end up with seam stacking and getting that annoying rubby-rubby sensation on your shoulders. Made from a 200gsm Australian merino and elastane blend, like with our lightweight long sleeve merino tees we have built in a big of extra length for easy tucking and full back (and front) coverage. No more cold lower back or bum crack!

Paired with our unisex merino thermal bottoms, our women's thermal tops will become your go-to when kitting up for most weather conditions you're likely to find in the Australia and New Zealand backcountry.

Comfortable Women's Thermal Top

These thermals are brilliant. Very comfortable and no wool itch (I am normally very sensitive to wool garment itch). The quality is far and away more superior to those I tried at the big name adventure companies (you know who they are). Measure up as per website instructions then go up 1 or 2 sizes as they do run small. Paul's customer service and support was absolutely brilliant and I am happy to be supporting an excellent well run small business that sells Australian made products.

Top quality long lasting

This is my 4th ottie product. Can’t get enough. Using them for work under my scrubs. They have all lasted the distance and are still like new. Just wanted more.

Excellent product and service. Couldn’t rate it highly enough. The quality of the long sleeve thermal top is way above standard and in my view unmatched in both locally and internationally manufactured goods. Its thick, warm and long and 100% Aussie. Whats more to like.
Highly recommend. Thanks Ottie. Keep it up.

Feels Like Quality 👌

So good to see a merino top that comes down over your hips to keep your lower back warm through the night. The thick feel of the top automatically makes you feel like this top was made to keep you warm and last the test of time.

They feel premium!

Love my new thermals. Wore them at Mt Buller yesterday. I went a size up based on measure instructs and glad I did. They are snug but they are meant to be. The band is really nice - looks quality. The fabric is thick and warm. Happy with purchase.

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.
