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.

Our Altitude range is designed to fit close to your body for maximum performance, so it’s tight but still soft, with plenty of give for extra comfort.

Our long sleeve Mongrel tops are some of our most popular, so it made sense we'd eventually get round to creating a Women’s Altitude ‘Mongrel’ Tee for when you want to strut your stuff in milder weather. Don’t let the fun name fool you, this is one seriously good, high performance Merino Tee. 

Wear this Merino T-shirt as part of our layering system for extra warmth, and when the temperature rises, you’ve got the perfect lightweight and breathable T-shirt that delivers the comfort and performance you need to go the distance.

Get in quick, all Mongrels are strictly limited edition and once they're gone, they're gone for good. 

Tag free, flatlock stitching, raglan sleeves eliminate chafe and maximize comfort. 

(For a more relaxed fit try our Ultra or Universal tops.)

Designed to be worn as a body tight ‘contact fit’ layer. 

New improved fit. Regular body length, shorter and looser than the Altitude long sleeve styles.

Model wears size medium.

Mongrel tshirt

Love my iomerino mongrel tshirt, perfect fit, comfy and keeps me warm but don't overheat. Love how it doesn't need a wash after every run, as it doesn't smell bad! Only slight problem is the wool is a bit itchy when it's new but that goes away after a couple of washes.

So cool

I love this t-shirt. May not be able to resist another one in another colour. Very comfortable and I think it will be perfect for carrying a backpack. I did buy a larger size because I prefer a looser fit.

Perfect T for all weather running.

Love this shirt, great fit and worn with arm sleeves is perfect for both summer and winter running. I recently wore the shirt with arm warmers to the winter Gloworm event which started at a chilly 1 degree, ran through a river and ended at a sunny 12 degrees. The shirt kept me warm, dried out quickly and was super comfy. 10/10 from me!

Great tee, fun colors

I bought the size based on where I fall in the size chart and I like how the tee fits, close but not clingy. I have been able to layer underneath it or use it as a base layer, and the color combinations are a lot of fun.

Great design, great fit, great colours.

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.
