Love it

Lovely soft Merino top, nice length to keep my bottom warm. Thumb holes are perfect .
I found the sizing to be a little roomier than my other IOMerino tops. I’ll be purchasing more of this top 💖

Thanks for the positive review, Helen!
Beautiful gloves

I can’t talk about durability, but these are a great soft warm glove. You’ll need a durable outer. I would ask the company to consider making a shelled glove. This as an inner would be very impressive, or for wearing around town and for running and walking.

Hi Andrew, glad to hear you're liking the gloves so far and thanks for the product suggestion. I agree, they make a great inner, especially for things like snow skiing with a waterproof glove over the top, but as you said, they're also great on their own when you don't need an outer layer! Best of both worlds!
Altitude neck tube

Extremely soft, suitable in Tasmanian winters, and great when you walk inside were it is warm neck does not break out in a sweat. Very comfortable and looks good on anyone, do not necessarily have to wear them only around the farm when working they are great to wear anywhere. Also as a head band they stay put and do not slide off and absorb sweat when exercising.

Thank you so much for your kind words, Susan. We really appreciate you taking the time out to share your experience with us.
So cute!

Very soft and comfy. Nice colours, and not too hot feeling.

Thanks for the kind words, kt!
Most under rated ioMerino product

Hands down the best ioMerino product, and that's saying a lot because I love a lot of your gear. The V neck is perfect for wearing day to day as well as for any activity. I don't know how I survived winter without this top. Super light weight and easy to layer. You never feel like you've got a million layers on, or that you cant bend your arms. If you get warm and have to take a layer off, the V neck top looks good on its own, not like wearing grandma thermals. The fabric is so soft you hardly know you're wear it, expect you're so warm and toasty. I've got all my friends on to this top. 11/10 would recommend.

Thank you so much for your awesome review, Emma. And thank you for recommending ioMerino to your friends, we really appreciate it.


good feel and keep out the elements. I recommend these arm warmers.

Thanks for recommending our arm warmers Gregory! Enjoy!
Wish I had these years ago before I bought skins and any other compression garment

I absolutely love them! they don't get too hot and are perfect for trail runs or any run on cold days. They are so much more comfortable than skins. You don't know you are wearing them. I also have worn them under jeans on really cold days for the very reason they are so light and you forget you are wearing them.

Thank you so much for your kind words, Jenni. We really appreciate you taking the time out to share your experience with us! We all feel the same way - what were we doing before we started wearing wool (specially ioMerino wool) !?!?
Great singlet

Very fine quality wool. As good as NZ competition.

Thanks for the awesome review, Andrew! We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you.
Good glove and terrific service

The gloves are very comfortable and feel great. Unfortunately, one glove developed a split along a hem line. One email to ioMerino resulted in a replacement pair being sent within 24 hours and no need to send the first pair back prior. Great customer service thanks ioMerio (and Emma in particular).

Thanks for your kind words, Scott. Glad to hear we could get the issue sorted for you quickly and easily. Enjoy your gloves.
Ultra Tee
Great Tee

Fits great, wicks moisture nicely and stretches every direction providing optimal comfort!

Hi Donald, thanks so much for the review! I agree, the Ultra Tee is one of my favourites too!. A great all rounder!
Looking after my delicate fingers on cold runs

I am loving these gloves as they envelope my hands and fingers gently with lovely soft merino wool keeping them just the right amount of toasty when setting off on a cold day/night run , they also pack down to near nothing when the temperature rises enough to remove the gloves
I am looking forward to buying some more ioMerino gear in the near future.

Thanks for the awesome review, Matt! We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you. Come back and shop with us soon. Cheers!
Great for riding

Purchased this for my partner to wear under his leathers whilst riding his motorbike. Fits him perfect. The thumb loops are great to stop the sleeves riding up the arm and the drop back hem is wonderful, it allows the top to stay tucked in whilst bending forward on the bike.

Glad to hear your partner likes the extra length in the Altitude Range. I've heard the women's Altitude Zip is pretty good too :)
Altitude Zip
It is not what I expected

The top I bought is well made but I think not the colour I ordered. I also dislike the ioMerino name tag that is sewn onto the front bottom left corner of the top. Firstly it looks cheap. Secondly I am not proud to wear your label.

Hi Ian, Thanks for reaching out and providing feedback for us. We're sorry to hear you weren't happy with your Altitude top and it wasn't what you expected. I checked your order and we have recorded that we sent you the Forest Green that you originally ordered, but if there has been a mix up please send us an email at customerservice@iomerino.com so we can follow this up and rectify this issue for you ASAP. If you would prefer a style without the ioMerino patch branding, the Ultra base layer range is a lot plainer and has minimal branding.
Not bad

Good tights would have preferred if they were thicker for warmth or more stretchy (they are a bit inbetween). Will wear and use them a lot

Hi Cassie, Thank you for your feedback on the leggings. We're always interested to hear from customers and what would really float their boat in terms of our Merino gear. I hope you still enjoy your new leggings, you might even be shocked with how warm they can be. As when it comes to staying warm and comfortable, bigger isn’t necessarily better. In fact, the experts agree lightweight layers are not only more comfortable, they can actually be more effective than bulky layers.

Good however...

I like the gloves but fro. All the products it was one that I was less happy with. Its a bit thin and because I have large hands, streaching the material a bit, allowing wind through when I am cycling.

Hi Andre, Thank you for your feedback about the gloves. We are always working on our products and fabrics so I'll be sure to pass on that there is still a need for larger sizes in the gloves.
Love them

I love the product, altought the price is a bit steep it is everything that it said on the website.

Hi Andre, thank you for taking the time to review your new tracksuit pants. Please feel free to send us an email if you'd like to pass on any feedback about something you've read on the website.

Great leggings

Very comfortable, warm & flattering to the figure. Another benefit of being wool is that at the end of their life they will bio-degrade not like the man-made fabrics that take hundreds of years to breakdown.

Marie, thanks for the review. Great to hear you're loving your new leggings. It's a win win with ioMerino - winning while you're wearing them and a win for the environment when you're ready to retire them!
Love my mongrel

This has quickly become a staple in my wardrobe. Love the quirky colours and the fit

Comfortable but worries about durability

I bought 3 boxers, these are my first ioMerino boxers. Importing them to Europe made them a bit expensive, but I like them.
They have a good length, are a bit loose fitting compared to the cotton boxers I have from other brands, but overall I like the fit.
They are soft and comfortable to wear, because of the longer length they don't bother during a run whereas shorter boxer ride up and start rubbing.
I am a bit worried that they fabric will start thinning quickly as I some chafing on the fabric at the inside of the thighsand this only after several hiking trips and some runs.
At the moment they are worth their money, now I need to see if they will last.

Great service

The help I received during the ordering process was excellent! Parcel arrived in less than 2 days & we love our purchases .

Thank you so much for your kind words, Helen. Enjoy your new gear!
Compression Leggins

Arrived on time. Fit like a glove. Feel good on. Warm as toast. Doing the job I bought them for. All 5 boxes ticked. That's a 5 star rating. I'd give you 6 Stars if we had a colour choice.

Damn! We would have loved to hit 6/5 star rating, I guess we'll just have to live with 5/5! We really appreciate you taking the time out to share your experience with us Shane—and we agree that some extra colours would be awesome. It's something we would really like to do, so you never know what you might see from us in the future!
Mongrel the magnificent

I love my mongrel top so much I am going to purchase another one. I wore it on my first ultramarathon and it was perfect. It kept me warm and dried very quickly when it rained. It will definitely be coming to the Berlin and New York marathons with me!

Awesome, Julia! Happy to hear the mongrel lived up to expectations! Best of luck with the Berlin and NY marathons. Send us some pictures of you running in your mongrel! We love to see what our customers get up to in their ioMerino.
Comfy and warm

Really glad I decided to try these socks they are so comfy and keep my feet warm on the freezing early morning walks. Worth the money!
Wish they made them in a shorter ankle sock

Hi Carly, thank you for taking the time to write a positive review on the multi sports socks. Happy to hear they were worth it. Noted about a shorter ankle sock version, its a great idea!
Seriously no pong

Okay, this sounds gross but... I wear the 1 pair of socks in my Doc Martin boots every day for work and then, I wear the same pair on Saturday for my morning Parkrun and then again for my afternoon sport. I just air them every night and they are good to go, absolutely no smell. Whatsoever. They are so good.

Less washing sounds like a win to me! Thanks for sharing your experience with us Sarah, glad to hear you're loving the socks.
Ultra Tee
🧡 so good 🧡

I bought the Ultra round neck T in orange. It is so vibrant. Maybe one day they might make a vibrant pink one - but for now - orange will do nicely. These and the altitude Ts are the only Ts I run in now. Team them up with a pair of iomerino arm warmers and you are good to go.
Slightly looser fit than the altitude Tshirt. I am normally a ladies size M 12/14 in tops. I pick M in the Ultra Range and L in the Altitude Range.

Happy to hear you're loving the Ultra Tees, Sarah! Fingers crossed for a bright pink version in the future!


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.
