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 and Ultra 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 is already designed as a more casual fit.

You know our world famous, best selling Mongrel top? Well this is the zip version of it. Just like the regular one, this is a bit of fun, super limited edition because it's made from bits and pieces of this season's colours, and a seriously good thermal Base Layer. Or a seriously good top for running or hiking or drinking that latte or whatever else you want to do in it.

The perfect combination of performance, warmth and comfort with a little bit of fun thrown in for good measure.  

Zip down when it’s mild, zip up and thumb loops on when the temperature drops.  The high collar also offers an extra level of warmth beyond the Women's Altitude Crew Neck Base Layer version of this top.

Flatlock stitching, raglan sleeves and tag free to eliminate chafe and maximize comfort. The drop back hem and extra body length is designed for tucking into your outer layers. Thumb loops keep your hands warm and stop your sleeves riding up when layering. 

Ultra Trail Australia mandatory gear approved thermals

Designed to be worn as a body tight ‘contact fit’ layer. Slightly looser than the Altitude long sleeve styles.

Drop back hem and extra length in body. 

Thumb loops. 

Model is 5'8" and wears size S.

Mongrel…love it

This is my second mongrel, love them both, first with a zip. Both have a great fit, so comfy and warm for those chilly Melbourne mornings

Mongrels are the best!

Thought I had my walking gear all sorted, then they brought out the mongrel zip and I had to have one of each😜 Super comfy, perfect weight for crisp Melbourne mornings and I love the quirky colour combos...they have been in constant rotation since arriving.

Love my Mongrel

This is my first mongrel and third ioMerino top. Love the zip feature, perfect for running in. Fit is true to size. Top is perfect for South Australian frosty mornings.

Mongrel bite

This wool jersey is not only warm and comfortable, it looks mean! Always a fan of I/O!

Comfort Plus

Having recently purchased my third mongrel, I can say honestly and from experience that it is the comfiest, best fit top I own. I love the colour and the addition of the zip neck. I’m usually a small but take a medium in io merino sizing.

Just love my mongrel!

After initially ordering a size too small I received my exchange in no time at all-Io is SO good at getting mail to come quickly! The mongrel is great-has hardly been off sine it arrived a week ago. Its comfy and long and fits over other layers and just right for this time of the year. Just a small hint-go up a couple of sizes with this one unless you want it to be skin tight.
Thanks Io-you've done it again!

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.
