Ultra Trail Australia mandatory gear approved thermal long sleeve top.  

The Women’s Altitude Zip Base Layer thermal takes natural temperature regulation to a whole new level. Designed to take you through a wide wide range of temperatures without overheating. Sleeves up, zip down when it’s warmer or full sun; zip up, sleeves down, thumb loops on when the temperature drops and you run into shade. You can put it on late afternoon when it starts to really cool down and be comfortable well into the night, rather than adding an extra layer later in the evening. 

This Base Layer Thermal top is the perfect combination of performance, warmth and comfort. This top is ultra lightweight and fold up really small in your pack (and will even fit into a zip lock sandwich bag!). 

This best seller has flat lock stitching, raglan sleeves and is tag free which eliminates chafe and maximises comfort. The high collar adds extra warmth around your neck and the thumb loops keep your hands warm. The fabric is breathable and moisture wicking to keep you cool and dry, odour resistant, super smooth and soft, and feels like a second skin. 

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

Drop back hem and extra length in body. 

Thumb loops 

Zip Neck

True to size. Model is 5'10" and wears size medium.

Love it

I love my 2 new tops. I'm a hiker so also appreciate how light they are. The sizes are very small. Medium, which I always wear, is very tight. 2nd top I bought a large and that is perfect. Good for people to be aware of.

Thanks for your review on sizing Ursula. Its always helpful for other customer when they are trying to find their prefect size. Glad to hear your love your new ioMerino gear!

Great running top for cooler weather

Great temperature regulation for autumn running and cool down when wet with sweat or rain. unzipping neck and pushing up sleeves really effective for cooling down when sun comes out. I tried not washing it for a week and it really did not smell bad. The only thing I would change would be to go up a size to M next time as the neck is quite firm when zipped up, but otherwise a great fit. Maybe

So comfortable

I can't believe how great this top is. The merino is so thin and warm but not too hot to run in. Can regulate the warmth easily by zipping up and tucking hands in. The fabric is soft and comfortable to wear and it doesn't get smelly after a sweaty run. Love it!

Thank you so much for your review Paula! We really appreciate it!

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.
