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, Ultra, and Horizon 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 and Horizon are already designed as a more casual fit.

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. The Women's Altitude Crew Neck Base Layer is the ‘go to’ thermal layer for just about any adventure and our all-time best seller. It’s the perfect thermal layer for core warmth when you’re layering up, yet versatile enough to be worn on its own in milder conditions.

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.

So comfy and warm. I am wearing it all the time underneath everything! Warm yet not bulky.

Love it!

This top is very warm yet thin enough to be worn under a fitted jacket. I have purchased 2 to date and am more than happy with the size and warmth.

Excellant product - will be ordering more in the future

Excellent quality

M

Wardrobe essential

I bought this for chilly morning dog walks but it's quickly become my 'wear every day' top. Comfy under a jumper or even on its own. The raglan sleeves mean no itchy seams under my arm. I'll be getting more of these - it's an essential top for autumn/winter. Ethics and transparency are amazing (I only purchase from ethical and sustainable businesses).

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.
