Hiking Socks

The only socks I wear for work, they feel great and never smell.

They are OK....thought they would be a bit thicker, pretty thin for the price considering they are made In Sri Lanka. Stitching seems good so far. My wool thermals are warmer though...

Celsius Tank
Very happy

I’ve not worn this but tried it on and I can’t wait for warmer times to wear it. Although, if you’re a runner you may love it any time of the year . I have 4 pieces of IO now, 2 mongrels a Tshirt and a tank all surperb quality from fabric to manufacture. No more of that other brand for me.

It was a birthday present and my daughter loved it.

No skimping on fabric!

Love my merino - the fabric is luxurious on my skin and yay, lots of length in body and arms. Definitely my new go to for merino's

Altitude 'Mongrel' Zip
Brodribb Penny (Melbourne, AU)
Great colours but very thin

The mongrel in my second io merino purchase. I love the colours and the cut but like my previous top it is very thin perhaps even thinner than my last one which fell apart within a year. I don't expect this one to last long either and the elastane blend means I can't put it in the worm farm when it's dead.
It certainly looks fantastic and I've had heaps of positive comments but probably won't buy from iO again unless they are heavily reduced as doesn't seem lime good value.

Hi Penny,
Given how unhappy you are, three stars is probably not a bad review so thanks for that. But we’d actually like to find out more about what’s gone wrong with your original mongrel. Our natural fabric won’t last forever like synthetics, (which is one of the GOOD things about them!), but they should definitely be lasting you longer than 12 months, so if you can reach out to customer service we’d love to have a chat and see if we can work out what the problem was and if there’s anything we can do to help. (It’s also worth mentioning the new Mongrels are made out of our usual fabrics so shouldn’t be any thinner, and while they are a definitely a relatively lightweight fabric, they’re designed that way and punch well above their weight when it comes to warmth.) Please contact hello@io-merino.com and we look forward to hearing from you.

Pace Compression Leggings - Original
Irene O'Daly (Adelaide, AU)
Good Fit

Met expectations as advertised.

Freedom Sweatpant
Caroline (Sydney, AU)
Very happy

Super comfy pants, very soft fabric. They do run small, I followed the advice to go up one size, I'm usually between a size 8 & 10, ordered a Medium and they're perfect.

Runs very small, go up at least 1 size

Love these, but they run really small, go up one or two sizes!

Altitude 'Mongrel' Zip
Just love it.

I love this shirt. I read previous reviews about sizing I normally wear medium sometimes large, I chose XL. I may have been ok with the large but I will take comfort over a size label any day. It’s very comfy, the natural fibre helps regulate my body heat., plus I get lots of compliments. It’s great quality, I am very happy with this purchase.
I spoke to a person over the phone and they couldn’t have been more helpful. I don’t think I’ll be buying that other brand anymore.

Altitude Tee
Marian (Maitland, AU)
Liked it so much I bought a 2nd

Bought it in green. It’s extremely soft. Washing was easy. So I bought it in purple. Love them both.

Ultra Zip
Sue Saunders (Launceston, AU)
Lightweight Warmth

I purchased this top to wear under my club jumper, it’s warm, smart, not too thick or bulky
Love it already, washes like a dream too

Ultra Zip
Avril Widdess (Brisbane, AU)

What a lovely warm merino top.
Colour is a beautiful red.
Quality is excellent with a great fabric feel.

Altitude Tights - Ready For Adventure
Michael Young (Sydney, AU)
Warm and Comfortable

Purchased to run the Kosciusko 100km later this year and wore them under my jeans to a freezing cold night game of footy ... perfect, fitted well and very toasty warm.

Altitude Crew - Run All The Trails
Natalie Bunworth (Adelaide, AU)
Perfect for the winter trail runs

With the Tower Trail Run in Mt Gambier it was time to be prepared for the cooler conditions. While the temperatures weren’t as cool as I expected this long sleeve top provided the perfect layer of warmth and comfort. Not too hot and breathable when the sun did peek out and warm enough as we descended to the valley floor.

Zodiac Triangle Crop
Sue Mews (Perth, AU)
Please accommodate larger breast

Very comfortable but larger cups would be ideal.

Universal Long Sleeve
Christina Knight (Perth, AU)
Just enough

Enough warmth under my work clothes

Ultra Zip
EVL (Gold Coast, AU)
Light and warm

My first impression was the lightness and warmth of this garment. It's absolutely perfect for travel as it takes up very little room and looks great on. I thinkI need another one!!
For reference I'm 158cm tall weighing 54kg. Size S is a perfect fit for me as a base layer.

Altitude Neck Warmer
David Beins (Sydney, AU)
Toasty warm

I bought 2 neck warmers after reading the ioMerino story and the overwhelmingly positive reviews about the product. I like that it’s made from Australian wool (prefer if it was also manufactured here, but Fiji is ok) and very happy that it does the job very well. Funnily enough it seems the colder the weather the warmer it gets!

Mullet Trail Socks
Fraser Rhind (Brisbane, AU)

Super comfy socks.

I love it!

Summit Easy Fit Hoodie
Delena Gaffney (Epping, AU)
Smaller size would have been better

Feels beautiful on. I only wish I had got the size smaller (I got the medium and that is usually my size) as my neck is quite exposed. The pockets are a bit saggy and I'm not a huge fan of the colour.

Yoga Pants
Delena Gaffney (Epping, AU)
So Comfy

This is my second pair of the yoga pants. The others are still perfect after about 2 years wear but I wanted another as they have become my day to day wear in winter either at home or out and about. They are a godsend as I find it difficult to find comfortable clothes that look good.
