Women's Merino Wool Leggings & Tights

For those who love being active as much as you love nature, our leggings and bike shorts deliver the ultimate combination of natural fabric and compression level performance. Created after years of extensive research and development, we’ve managed to produce a world first Merino Compression fabric that is naturally, breathable, temperature regulating and odour resistant. 

And for the ultimate in lightweight base layer comfort you're going to want to add a pair of our go-to thermal tights to your activewear kit - they'll help keep you warm when it's cold and cool when it's warm for year-round comfort.

The Pace range combines all the benefits you expect from our high-performance merino fabrics, with the high performance of compression garments. Made from a merino-rich 76% superfine Australian Merino Wool, the fabric combines all the natural benefits of our finest MicroMerino® fabrics with 15% Elastane for compression, lift and support; and 9% Nylon for added durability. 

The Altitude Tights are a classic thermal leggings style and great for warmer to cool temperatures as base layer pants. Part of our Altitude Range, these tights are ‘contact fit’ to maximise thermal properties and sit flat under other layers. 

No marketing hype, no exaggerated claims, just the genuine benefits of premium, natural merino for the ultimate in comfort and performance in any weather.


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.
