Stride Tracksuit Pants
Claire A (Adelaide, AU)
Almost perfect

There’s so many things to love about these pants: how soft they are, so comfortable, how warm they are but still lightweight. Unfortunately a few things stop them from being perfect.

First - the pockets are too shallow, even a tissue I had in there fell out when I sat down let alone anything more substantial. Just a few more centimetres would make a difference.

Second - I’ve had significant pilling already between the thighs in the short time I’ve had them which is frustrating and I’m concerned on how long they’ll last before wearing out due to how thin they are.

Third - the men’s version of these have a drawstring but the same option isn’t available on the women’s. Would be good if this could be offered as depending on what you’re doing a drawstring can be very handy.

I still love the pants and have already bought a second pair in a different colour as they’re so versatile; from walking the dogs, doing work around the house to low key casual catch ups. But I would buy them in every colour if they could fix a couple of the issues above.

Hi there Claire,

Thanks so much for your review. We've gotten in contact with you directly. :)

All the best,

Ultra Zip

Love it

Bought the Ultra Zip in Grey and I absolutely love it. This is my first IOMerino product and I’m really impressed by the quality. Feels soft, it’s super warm and fits really well. On the fit, I’m 5,11 (180cm) 75kg athletic build and while the medium fit was perfect across the shoulders, it would ride up if I put my hands up and was just a bit too tight to be comfortable for running and layering when climbing/mountaineering. I sized up to a large and it’s perfect.

Highly recommend this.

Local quality

I love my new pants and I live that I could buy them locally I needed to exchange them for a larger size, my underestimating my size, snd just popped down to Adelaide to do so, though I have to say they were very prompt in sending them.

Awesome top!

I just recently bought this top to replace a similar style synthetic one. The difference is night and day! I was getting hot, sweaty and itchy under the synthetics on long hikes. The merino fabric feels so much nicer on my skin and breathes so well, the comfort levels have improved 10 fold! Also love the zip for chest cooling and the thumb loops to protect the backs of my hands from the sun. Well done IO 👏🏼

Altitude Tee - Southern Cross

Worth the expense

Best and most comfortable merino clothing for the UK and Canada winter. A must buy is the base layers. Tops and leggings. Very happy with my purchase.
Easy to care.
Can't wait to use my gear for next trip to Finland 2025.

Fit for purpose. As used by e72.au.

Great Fit

Exactly what I was looking for. Even better it’s made in Oz.

All set for winter!

Fantastic for the Camino/long hikes

I wore this tee on the Camino and loved it. I hand washed it every second night and by morning it was always dry. I love the dazzling blue colour, the higher neckline was great for preventing sunburn and the sleeve length was perfect. I only had two tees with me for 42 days and I never tired of wearing this tee. It has kept its shape and has plenty more wear left in it.

Walked the Camino in them

Fantastic for hiking and everyday use. I bought two pairs of the bikini briefs for the Camino (40 days of walking) and they were fantastic. They dry really quickly. I would hand wash out a pair at night, roll them in a towel to get the excess moisture out, hang them up and by morning they were always dry. The hot pink colour made them easy to find in my pack too. Love them!

Altitude Briefs Seconds
Lucinda Hallows U (Sydney, AU)
great material - slightly strange fit

These are great in the sense of the material and colcour but they dont quite fit in the right places well. would buy again though maybe a different cut

Hi there Lucinda,

Thank you so much for your review. :)

As we mention in the product description, these ones are on clearance and 'Seconds' because there was a bit of a mess up when making these ones, and so the cut is much lower than our other Altitude Brief - Ready for Adventure.

We're glad you love the colour and material.

All the best,

Unfortunately too "ultra"

I normally wear a size M. I wear the boxer shorts from iO (size M) often and very happily. I should probably have chosen a size larger for this model. The quality is top but in my case unfortunately not stretchy enough and therefore too uncomfortable for everyday wear.

Best socks in my drawer!

My favourite socks! Just a pleasure to wear, breathable, soft, comfy!

The boxers themselves are excellent. Great material and a great fit. What set ioMerino apart was the proactive customer service. I was very impressed

So comfy

Although these are pricey for underwear, they're by far and away the most comfortable underwear I've ever worn. Synthetics are no good for me (cause itching) but these are completely itch free!

Best ever socks

These are the best socks I have ever had. Cushioned and extremely comfortable, they fit in my shoes like much thinner synthetic socks, they can be worn for days before they need washing and they don’t walk down into my shoes.

Altitude 'Mongrel'
Judi Moncur (Beechworth, AU)
Love the style but comes up very small

I really like the colours- makes for a much more interesting top than the usual. I found this came up really small compared to other merino outdoor tops I’ve bought- just surprised that no other reviewers have said it was true to size. I’m normally a size 8 , 55kg with narrow torso, so I ordered a size S, my usual size - but I couldn’t even get it on, so exchanged for a size M. IoMerino we’re very helpful and handled the exchange quickly. The size M has just arrived, still a bit tight, but wearable, though I prefer a bit of room in these tops and to allow for shrinking after washing - seems ridiculous to get a Large, but I might have to do that next time. Have some of them been mislabelled? Loses one star for the sizing.

Hi there Judi,

With the sizing of our Mongrel items, they are part of our 'Contact Fit' range, and so are designed to hug very close to the body.

You won't have to worry about sizing up to allow for shrinkage thankfully, as our wool has been superwashed, and so doesn't shrink.

All the best,

Goldilocks fit…

I’m a size 6-8 and bought this in a size XS which is just the right length for me - I’m 162cm tall/5 feet 3 inches. Not too loose, not too fitted, just right, and the Merino is a nice weight. Some Merino tees are too thin and are closer to underwear than teeshirts. This is a good mid-weight.
I bought this in the red (chili) and I like it enough to be considering buying another one or two in different colours. My first iomerino tee wont be my last!

A great investment

This jumper is going to be my new best friend, even in Australian spring/autumn (or Melbourne summer!).
In Norway at present - well and truly minus- and it performs wonderfully as a layer, or a quite-dressy top indoors.
I'm really pleased with the quality, and it's NOT made in China!

I've been searching for these

I've been searching for high-waist (check) medium-weight (check) merino wool (check) bootcut (check) leggings, and these are perfect. The only thing that would make them better would be a phone pocket. They are soft and don't stretch out or bag-- even after multiple wears. I will purchase ioMerino again, for sure.

These are comfy, I'm happy. In terms of sizing I went with a size L as a size 12 normally and I think that works okay -- though if you're on the slimmer end of that size you might prefer a M for a more snug fit.
