Super soft, ultra comfortable, lightweight and breathable.

Tag-free, flatlock stitching and raglan sleeves help eliminate chafe and maximise 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. The lightweight hood adds extra warmth around your head and neck and fits under a helmet with ease.

Perfect little, snuggly compact warm me up on a cold morning in home outerwear

I love the hood which covers most of my face comfortably and is a big boon or my bald head! It is so soft!
This piece is going traveling with me as the outerwear on planes. Also love the long sleeves and thumb hole for keeping hands warm.

The best thing I own

It's warm but not too warm, never gets stinky even though I wash it maybe once a month. Fits great... nice and thin. Plus it has a hood when things get cold & windy at Mammoth Mountain and it fits under the helmet nicely. Can't say enough good things about the altitude hooded zip.

Awesome!

A few years back, I bought a similar hooded merino top from another company and wore it constantly while walking the Camino. Sadly, it developed holes and was no longer available. Imagine my delight to find the Altitude Hooded Zip at ioMerino. Light, warm, comfortable, exceptional quality and an Aussie company to boot. I’m not a ‘pink’ girl, so bought the ‘black’ mens instead. Perfect! Super quick delivery too. I’m one very happy customer and will definitely be buying more.

Fits well and keeps me warm

I got this for winter runs. It hasn't been super cold where I live this year, but I did get to run in ~31 degrees the other day (in the evening). I usually wear a wool hat that my wife knitted but I experimented with sticking to the hood, which is perfect for keeping my ears warm for the first few miles. I felt about the same for the entire run after warming up, which is a huge improvement over the synthetic hoodie I was wearing at these temps, which feels less warm near the end of the run.

It did seem to need a wash beforehand. I wore it without washing and it had a bit of an odor that didn't reappear after a trip through the washing machine.

Wow that's chilly! With your Hooded Zip and Compression Leggings you should be toasty!

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.
