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.

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 wears size Medium.

Fits small

I ordered the XLand it is tight. I normally wear a Large, never an XL.

I would say in Canadian sizes, it is more like a medium or large slim fit. Not very flattering if you have any love handles. It is cute and I hope I can lose enough weight to wear it one day.

Love it!

Not only are the colours amazing, but it is so comfortable. I wear mine to the gym and walking. It's a great fit and really comfortable, I also get several wears out of it before washing. Love the fact that it is made from all the left over bits.

Comfortable and colourful!

I’ll admit the bright colours of the Altitude’Mongrel’ zip top were the main drawcard to buying it but once it arrived and I tried it on I knew I’d made the right decision. The quality is exceptional and the fit is perfect for my petite frame (I’m size 6-8 and 165m tall), especially the slightly longer length which I like over my lower back and hips in cold weather. I wore it on a 48 km coastal fundraising walk recently and it performed brilliantly - warm and super comfortable against my skin with no irritation or itching which is exactly what I’d expect from a superfine Merino product. Also love the fact that I’m buying from a local company - will definitely buy more ioMerino clothing in the future!

love the 3/4 zip mongrel

Was excited to see the different colour schemes and the variety of mongrel tops to chose from. It arrived very quickly and I was able to wear it during the Great Ocean Road event. I participated in the 23km walk from Kennett River to Apollo bay. I was warm and comfortable during the walk. The sleeves and torso are a good length. I'm an Aussie size 12 and find the Large fits me well. Love it!

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.
