The Altitude thermal Tops are longer in the body and have a drop back hem to tuck into your outer layers so you don’t have exposed cold spots when you’re on the go. The thumb loops keep your hands warm and make layering easy. Flatlock stitching, raglan sleeves and tag free labels help eliminate chafe and maximize comfort on the slopes all day.  

Our range of snow thermals and accessories are naturally breathable, which means they'll keep you warm while you're on that freezing chairlift, but stop you overheating when you’re in action. They also don't get stinky and sweaty like synthetics will.

Our high-performance Merino Wool thermals are a must for all of winter's snow adventures.

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.
