Love my new T

Bought the altitude T-shirt - felt itchy first try on but once it’s washed and worn a couple of times it’s soft and so good to wear running - great shape and cut - I’ll be buying more in that style 👍🏼

My new favourite

I am always hesitant about buying clothes online as I am quite tall and slim so often t-shirts are not long enough for me, or they are long enough but way too wide. But when my new altitude southern cross t-shirt arrived and I tried it on, I couldn't believe it! It fit absolutely perfectly!! Long enough in the body and the width and sleeve shape were a perfect fit. It automatically became my new favourite t-shirt. It is my go-to shirt when travelling. I wear it on the long plane trips as it is super comfortable and it doesn't smell!!! Even after 14 hours on a hot plane!!! I admit I will wear it multiple days in a row without washing it. Because I can! I highly, highly recomme

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.
