Psst... Our undies are individually wrapped in compostable polybags. So,  if you buy a bundle, open one, and the size isn't right you can return the unopened pairs for a partial exchange. Obviously, being undies, if they're worn we can't exchange or refund.


Imagine all the things that you love in your merino tees in the form of underwear?

Introducing the new Ottie Merino men's merino wool boxer short. (Actually, they're not just for men, they're unisex really.) The softest and comfiest boxer briefs (yep, they're a trunk style so they stay close to the skin and don't bunch or chafe) you'll ever own. Designed for hikers, travellers, mountain bikers, skiers—anyone that wants a high performance and comfy-as-heck pair of dacks, really. Our merino underwear boast a cooler, lighter, and silkier feel thanks to our superfine 150gsm Australian merino wool combined with TENCEL™, a fibre spun from wood pulp, famous for its incredibly fine nanofibrils. That's code for comfortable and functional. 

Ethically made in Australia (in Melbourne of course), these merino underwear are designed for those adventures where you mightn't be able to change your jocks as often as is civilised but will become your every day choice. Great if you're travelling too and the only 'washing machine' you have access to is the hotel sink!

As for the undies, due to the obvious hygiene reasons we can't do exchanges or change-of-mind returns on underwear that have been worn or tried on. Once it's out of the packaging and/or the swing tags are removed, they're yours.

However, if your undies are faulty or we have stuffed something up, of course our standard returns policy kicks in. Whatever the Australian Consumer Law says, we'll do as a minimum.

If you buy a bundle and try on 1 pair and the others remain in their packaging with swing tags attached, they'll be AOK to return or exchange those.

No thanks

The styling and fit of these is short tights and not boxers. Who wants tight boxers? Did women design these? The medium-size waste measures 32 cm. Not medium at all. I mistakenly opened all 3 packages before I realised they were too constricting to wear comfortably.
Then I looked at the label and they are only 40% merino wool. The rest is synthetic. You advertise "100% Aussie merino wool" which gives the mistaken impression that they are 100% merino.
I then mistakenly ordered large before I noticed that they are only 40% merino wool so they will the returned unopened thanks very much. I will also send you back the three medium that I opened. You can do what you like with them.

Thanks for the review and the feedback, Richard. I've sent you an email also.

I designed these. And I was the wear tester for them. These are purposely a 'trunk' style boxer design. Mightn't be clear from the pic or from the product description, but we'll update this. More photos to come soon.

For physical activity, like hiking, a trunk design is generally preferable as they better keep things in place, and the fabric doesn't move around, causing chafing. But we get it, that's not for everyone.

As for the fabric composition, we are quite clear on these being a blend. Pure merino boxers would quickly lose stretch, fall out of shape, and be horrible to wear. I have updated the product pages on our website to show the % composition, to be a bit clearer.

Again, thanks for your review. I've sent you an email and we'll resolve this there.
