Altitude Range - 'Contact Fit'

The Altitude range is designed to be a tight, but comfortable, fit. If you size up it will give you a little extra room, but it will still hug your body as that’s what this range is designed to do. If you want a looser fit consider the Ultra or Universal range.

Universal and Ultra Range - 'Regular Fit'

These garments are designed true to size, but going up a size in the Ultra will give it a slightly looser fit, whilst remaining sporty. The Universal is already designed as a more casual fit.

This top is guaranteed to help keep you comfortable for longer come rain, hail, shine or all of the above. And as a three-time supplier of official UTA mandatory gear compliant thermals, you can be sure our gear is the real deal.

While merino is best known for keeping you warm when it's cold, its natural breathability and temperature-regulation also helps keep you comfortable when it's warm. So no matter what time of year, or what mother nature is dishing up, whether you're training or racing, you'll be good to go with io.

If you're more of a Tshirt person than a long sleeve top person, the Women's Ultra Merino Tee is the way to go, because unlike ordinary Tees, it will still deliver a level of comfort across a wide variety of conditions.

It's soft, comfortable, and combines all the natural benefits of our finest MicroMerino® fabrics with just enough nylon to create our most durable fabric ever to withstand the most demanding adventures.

It's also breathable, moisture wicking, temperature regulating, odour-resistant, and designed specifically with Ultra Runners in mind.

This true high-performance garment is packed with extra performance features including tag-free labels and flatlock stitching to help eliminate chafe and maximize comfort, and reflective trims have been added for extra safety in low light.

If you're not sure what the weather's going to dish up, team it up with a pair of our Newton Merino Arm Warmers and you'll be ready for just about anything

Awesome

One of my specific reasons for buying the polo, apart from wearing it casually, I wear it under my yellow protective clothing as a volunteer firefighter. It is extremely comfortable in very hot conditions as it does not stick to your skin when sweating heavily and with the wicking ability helps with managing my body heat. Being wool it also gives that second level of protection against burn injuries.

Hiking Socks

Amazing!

I have stopped wearing leggings under my skirts for awhile now because of all the synthetic fibers and I decided to get these after a very long search to find the best. After about 1.5 months of searching and reading reviews I decided to get these. I followed the size guide and I found a perfect fit, I never want to take them off. Now I wear long, mostly ankle length skirts and I run in them so I sweat and I sweat a lot but these are amazing. I also have very stretched out skin from having children and these really hold things tight so my skin doesn't hurt when I run or itch. So pleased! I'm super excited to get a second pair but I need to save a bit for them. They also keep their shape after a couple days. I'm so thankful!

Great trackies

These track pants are a delight to wear. They are light comfortable and easy to wear during any activity. They also wash well. Also smart enough to wear while just out and about.

Stride Tracksuit Pants

Perfect for travel

These yoga pants were perfect for my recent trip to the UK. Comfortable all the way during the long flight and perfect for the cold weather there on arrival. I wore them the whole time I was away and they didn’t crease, lose shape or go baggy in the knees! Am about to buy another pair…

the best trunks on the market

being an avid supporter of the merino industry and io merino product i purchased 3 pairs of the mens trunks about 12 months ago- it was not long before i dreaded wearing the cotton brands i was wearing prior to that. I then purchased enough IO mens trunks to ensure i had 100% comfort 100% of the time.

Fabulous hoodie and amazing service!

I’ve been after a good hoodie for a while and had my eye on this. I bit the bullet on Monday, called up, got great service over the phone and when I got home from work today it had arrived! The hoodie itself is feels so soft, fits great and the quality is amazing. Now considering buying a different color! Thanks IO!

Summit Zip Hoodie

New Running Long Sleeve

Only used a couple of times but it’s great. Comfortable fit keeps me warmer than a t shirt and the thumb holes help keep fingers warmer on frigid hills mornings. Time will tell for durability. Love the colour (mint I think)
