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.

Gorgeous fit and comfy material to run in. Zero chafe even on long runs (20km+) which is a first for me!

Good fabric

Nice style and fit

Also super fast shipping. Merino wool is the only wool I can tolerate wearing. However, compared to my shirts from other brands, these feel a bit scratchy. Hoping that will diminish because otherwise really like the shirts.

Cute tee!

Great tee. Glad I sized up as it definitely would have been too snug in my regular size!

Very soft

So comfortable, soft and warm

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.
