    • What does 'io' stand for?

      One of the questions we get asked quite a lot is “What does ‘io’ stand for?”. And it’s a fair enough question.

      At io, we think it's Incredible Outside. Does this mean io is Incredible Outside or that outside is incredible and yes, yes it does. Both of those things. 

      It's why we say you should 'go with io' - because it's Incredible Outside. Whether that's on the trails, in the mountains, on the water - literally anywhere Outside. 

      When you wear our incredible, comfortable, temperature regulating outdoor clothing, you'll enjoy yourself more by being prepared for just about anything, and staying comfortable for longer.

      We’ve literally never quite understood why people who love nature and natural things so much would then go and dress in 'plastic' - because that's basically what synthetic fabrics are. OK, yes, there are times when there are no natural alternatives. We’ll admit if you need good waterproofs, you’re probably going to have to bite the bullet and wear something synthetic. But if you’re looking to say comfortable and warm, why choose plastic when you can choose one of Mother Nature’s best natural fibres: Merino wool.

      And if you’re going to choose Merino, then it would only make sense to choose the good stuff. Australia produces some of the best Merino wool in the world, and we use exclusively Australian Merino wool. Not the coarse, scratchy stuff. Not the cheap stuff. We use the best of it. And with 140+ years of wool-heritage behind us, we think you’ll be hard pressed to find another company who knows more about wool than we do.

      They might have fancier ads. Or sexier patterns printed on their gear. But they won’t know more about wool than we do, or make garments that will feel and perform better than ours. Which is why we’re proud that our customers are the ones that value quality and performance over glitzy marketing. That our customers are into natural over synthetics. And are into the outdoors as much as we are. The true Outsiders. 

      So there you go, if you’ve ever wondered what the ‘io’ stands for, and what we're all about, now you know. Even though the 'merino' word isn't part of our official name anymore, it's still absolutely a part of everything we do, with each and every one of our garments given super powers by the natural miracle that is the premium Australian merino wool we use. 

      See you Outside!

      Cute

      I ordered one size up as advised in the product description and it fits perfectly. I love the stripes. Have not yet worn it on a run due to weather but I love wool and expect it to perform well.

      Perfect T

      I’ve not worn a T in my life that works like the IO. From Exmouth to Adelaide this T worked as described by the company

      Great for a cold weekend away (at Wonderland), or smart to wear at work with a Pinnacle Top. Such good quality, I bought 2 if each. The colour has not faded after 3 years wear.

      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.
