Inside ioMerino - All You Need to Know About Merino Wool 

If you’ve made it to this page, you’ve either taken a very wrong turn or you actually want to know a bit about who we are, what we do, and how we do it. In which case, hi, we’re ioMerino!

We’re certainly not the biggest merino company out there, and nor are we particularly interested in size. We are, however, really keen to be one of the best in the world. So while some companies have a zillion different products and it’s all about selling as much stuff as possible to as many people as possible, we tend to have just the absolute best quality stuff you really need to keep you comfortable and warm in this adventure we call ‘life’.

If you’re reading this now, then you’ve already proven you’re exactly the kind of person who’ll love ioMerino because while some people just go with the biggest or most popular brand out there, you’ve shown you’re prepared to dig a little deeper, discover something new, and go with something genuinely different. And genuinely better.

So please, have a look around and, as always, if there’s anything you need to know or need help with, feel free to contact our customer service team any time. They don’t work 24 hours a day - we give them time off to go and do the things they love as well, but will usually get back to you fairly quickly. And they’re not just random customer service drones, they’re real people who know our products inside out and wear it themselves - although not necessarily inside out.


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.
