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, Ultra, and Horizon 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 and Horizon are already designed as a more casual fit.

Lovely

Lovely fit. Soft fabric. Smooth flatlock seams. And it's even (just) long enough for my extremely long torso. I'm 184cm tall, and all torso :).

Racerback singlet

Love love LOVE! I wear it throughout the year - cool in summer and great for layering in winter. Beautiful fit, not scratchy. Very comfortable…and they don’t fade!

P
Penny S. (Perth, AU)
Very comfortable

Bought for an extra warmth layer and emergency swimming top when backpacking. Very nice and comfortable.

E

Essential

Must have for the wardrobe!Perfect for layering and looks great on it’s own. Very versatile with all the merino plusses. All round winner

H
Heather Griffiths (Melbourne, AU)
Great colour options

I was worried this might be a little short for my extra long body, but am really happy with its length and that it doesn’t ride up. Nice and snug and beautiful colours to choose from.

K
Kim (Melbourne, AU)
Great quality tank

I purchased to use as a base layer for cycling. Excellent quality and fit, I’m 5”1 and 45 kg and purchased the xs.
I have very sensitive skin and have found ioMerino to be very soft and not an ounce of itch which is awesome.

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.
