Whether you're on the trails or the slopes, the rivers or the mountains, you're going to want to add a pair of the Altitude Base Layer Thermal Tights to your kit. Made with superfine Australian Merino Wool, these tights are incredibly soft and will help keep you warm when it's cold and cool when it's warm for year-round comfort, no matter what the weather. So when you’re out in the elements being active, your legs will stay toasty warm without overheating as they’re prone to do in stinky synthetics.

The Altitude Tights are the same thickness as the Altitude tops. They are a classic thermal leggings style and great for warmer to cool temperatures as base layer pants. 

Tag-free labels, flatlock stitching and a flexible and ultra-soft ioMerino elasticated waistband help eliminate chafe and maximize comfort. The mid-rise style works perfectly with the Altitude Base Layer tops to ensure no exposed cold spots when you're on the go.

Ultra Trail Australia mandatory gear approved thermals.

Designed to be worn as a body tight ‘contact fit’ layer. 

Mid Rise. 

True to size. Model is 6'2" and wears size medium.

Great warmth for the weight!

Very pleased with these as they are light and thin but very warm under my wind pants. A perfect combo for our New England winter.

Warmth and comfort

Trekked overnight in these leggings - didn't even notice they were there, just kept me happily warm - and the scratchy bushes didn't create any holes - great result!

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.
