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.

Comfortable and colourful

I bought both Mongrel short sleeve and long sleeve. So far I’ve only had a chance to wear the long-sleeve and I love it. I like that there’s a bit more room in the sleeves so they’re not skin tight, and I didn’t realise there’s a thumb hole which I love (good length for colder days). I would have liked a bit more fabric in the boob area, but otherwise the general fit is good. The mix of colours and stripes is a delight.

Amazing top

I’m so happy with this top! Thankyou io! The fabric is wonderfully soft and the colours are such fun - I have black and grey base layers and feel much brighter and happier in this! The size chart is spot on. Since receiving this I’ve ordered more from io, really like their philosophy and products are amazing.
Traveling to Alaska in May, and the UK next year. I’m carefully building a small travel wardrobe (which I’ve already started to wear ALL the time - these clothes are so so comfy!) I am even more thankful to have found a local company to support.

Warm and funky

My order was processed and arrived quickly. I love that the Mongrel has some colour to add to the generally drab range available for winter. I love that it doesn’t make my skin prickle and itch. Highly recommended.

Mongrel

This thermal is so soft, no wool ‘itch’ I find it incredibly warm and comfortable, long enough in the body to tuck into pants. Customer service was amazing
Highly recommend this company

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.
