Best knickers!

My new favouritest knickers - good coverage and they don't ride up.

Thanks Sarah!
Very nice

Soft, light and comfortable.

Great Pants

Love these pants. Comfortable, light, warm and they don't ride down. I'll be getting some more.

Great hat!

I was very impressed about how thick and soft the hat is. It’s the perfect hat for harsh winters in NY, USA

Perfect for my needs

I’m going to Alaska- above the Arctic Circle for work in January and February. This is the perfect base layer. The fit is just what I wanted. The product is soft and beautifully made. I live in the U. S. but had to go to Australia to get the perfect product for my needs.

Great to hear. Have a great trip!
Ultra Tee
Superior gear

I’ve been meaning to write this review since Oct 2019 when I completed the Blackall 100 in Qld using the Ultra T all day (and night) long. I can’t recommend it highly enough. It is a superior piece of outdoor equipment, especially if you’re slogging it out for 20+ hrs as I was. In humidity, heat, cool evening air and thunderstorms, the Ultra T was super comfortable, chafe free and like a second skin that responded to every step of the journey. You want to know you have gear that does what it promises when you’re out on a long adventure, iO Merino certainly does. I’ll be buying more in the future. Great product. Worth every cent. Cheers!

Hi Chris, glad to hear it's performing as it's designed to! Congratulations on completing your Ultra too!
Most comfy

It’s the most comfortable thing I ever wear . It’s so soft and warm , and it feels great to put your hands in the pockets

Great to hear Bryan!

Brilliant kit fits the bill in every way descibed plus ember esisant while fighting ember attacks.

Glad to hear it's keeping you safe!
Another great product

In my 8th year of the process of switching all my important gear to wool. IO Merino is definitely the best brand of the 5 brands I have tried. I highly recommend this company in general and these boxers in particular!

Thanks for your review Casey!
Summit Vest

Extremely well made, beautifully finished and fitted for the female figure. I really like this vest, it is a pleasure to wear and is of the quality of I have come to expect from ioMerino. The swift delivery is also a bonus.

Glad to hear!
Best Base layers ever.

I have always had problems with temperatures that change from morning to evening. These are excellent for keeping me comfortable all day. Warmth and coolness when needed. I have purchased many tops and two bottoms. Just this season so i have to wait til next season to add more.to my wardrobe. Also great to wear as base layer in winter when sleeping.

Thanks Sharilyn!
comfy and warm!!

I bought a men's small and it fits great (I'm 5'7'' 130lbs - 60kgs). Really warm and light - washes well - no twists or kinks like I had with the top that I purchased.

Some are made in China!

They are nice, smooth, warm, well fit, comfortable, etc. like many things I like from Iomerino. The shocking thing is that I recently bough a black pair, and they were made in China! I don’t think the quality is suffering but I thought all Iomerino items were made in Fiji. China dominates the world in just about everything. I would prefer not buying things made in China if I can help it. Please put the information on the web to help one make decisions in buying the products.

The good news is we moved away from manufacturing in China a while back now for various reasons, and now predominantly manufacture out of Fiji where we have much better guarantees around ethical production. Rest assured your garment will still be made from our premium Australian wool, knitted into fabric here in Australia and made to our usual exacting standards, it just must have been manufactured before the shift.
The best t-shirt

18 years ago I bought their almost identical t-shirt in Mammoth, CA at a snowboard shop. Since then I've been waiting for IoMerino to bring it back because the original one I still wear even though it is starting to wear through because it's my favorite shirt. I even emailed them about bringing it back maybe a year ago. Stoked they did, I purchased 2, and the new one is even nicer than the OG.

Ultra Tee

Day 9 of wearing this every day hiking the Te Araroa trail in New Zealand and the shirt is super comfortable and best of all doesn't smell. A quick rinse and it dries quickly. It is pilling a bit where my backpack rubs and I got a hole in it (a stick went through it) but perfect so far. Will see how it goes the rest of the trip!

Great to hear! Enjoy the rest of your walk.
Vital crew neck

Perfect! Nothing more needs to be said.

Merino compression leggings

Comfortable, warm and look good.

Glad to hear you like them!

I love these pants. They are definitely compression and also warm! Will Definitely buy again! Wish you had the southern cross yoga pants still in stock!


I love these socks!

Happy buyer

I have been buying your garments for some years now. Great for online ease of purchasing and I love everything I have bought and had the pleasure of wearing. Beautiful comfortable and long wearing garments. Love your brand and products Thank you

Great leggings

These are so comfortable! I have used them on long haul flights and out bush and they have been fantastic.

Altitude 'Mongrel'
Altitude Mongrel

Love it so far.....hope it wears well!

Great all-round top for cool climates.

Comfortable, warm and stylish. Great for Tasmania's changeable weather.

Petite cyclist needs to be warm

Excellent product. Couldn't find arm warmers small enough in US. Stretch, fit, and quality are perfect. BTW, recommended by another petite cyclist.

Great to hear! Thanks for your review.

Excellent quality, light weight and cool for summer fitness!!

Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.

Ethically Made. Ethically Sourced. Perfectly Natural.
