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

No more cold lower back or bum crack!

Great quality thermal.

Love the extra length on the body. I found the arm sleeves a bit too tight for me. Really like the neck line. It’s roomy at the throat.

I ordered a large size as I dont like my clothes too tight across my body. The fabric is fabulous however the length of the sleeves are way too long and neck is a tad on the big side.

Very warm and good fit. I like the extra length! The size / measurement instructions worked very well.
Although I ticked hiking below as the purpose, I will also use it for everyday wear and travel - need more boxes!!

This sounds as if it is a complaint, it is not, and I don't want it up. I got one too small, so meed to return, where do I send it? Also, on your size chart, it did not make sense to me,
Please, I do not want to complain..

Women's Thermal Top

Initially ordered the XS. Perfect length but way too tight and bulky in the shoulders and sleeves. I went up two sizes to account for shrinkage, but the overall fit is probably now too loose and long for a thermal although the fit and the length in the sleeves is much better.


The quality of the top is excellent and I am 100% happy with my purchase. The quality exceeds any other thermal I have purchased

Womens Merino Thermal Top

This is my second top I have purchased, as they are so comfortable and I find perfect for everyday wear.

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.
