A world first: full climate control

If you’ve ever dreamed of owning a top or T-shirt than can get you through all sorts of weather conditions, this is it. Our new range of thermostat controlled tops are so advanced, you can dial up the warmth if and when you need it. Imagine starting the day in warm weather, in a T-shirt that will keep you cool, then dialling up the warmth as the temperature drops. That’s exactly what these can do. Thanks to revolutionary new technology, a simple push of a button allows you to dial in your desired temperature so you’ll stay comfortable for longer, through all sorts of weather conditions. 


Complete comfort. Always.

The natural nanotech control panel is 100% waterproof, washable, flexible, and ’soft touch’, so you won't even know it’s there. Unless you need it. Simply push the ‘up’ or ‘down’ buttons to select the temperature and your T-shirt will do the rest, helping you stay completely comfortable. Always.


First on, and off, the planet.

This world first technology has been made available courtesy of a unique collaboration between the Aeronautics Research Mission Directorate at NASA, and our very own ioLab. First developed when looking at ways to keep astronauts comfortable in outer space, you can now use a consumer version of the exact same technology to keep you comfortable in the outdoors. ioMerino has a long history of innovation in natural merino wool fabrics that are some of the most comfortable on the planet, so it should hardly be surprising that we can now deliver these advances to you in our latest fabrics.


Available now. Really. Naturally.

If you’re still wondering if this is a real thing, wonder no longer. The temperature control is, even if the temperature control panel is not. That’s right, with our awesome, natural, MicroMerino® fabrics, you get natural temperature regulation that keeps you comfortable through warm and cold weather, without the need for any technology at all. It’s all delivered naturally, courtesy of mother nature. Still confused? Don’t be. It’s April 1st. There is no Control Panel. But buy any of our awesome MicroMerino® layers, and you really will get a similar level of comfort. Naturally. Really.


Click here to shop our Keystone range of casual fit layers, our Vital ‘second skin’ layers, or our Altitude ‘contact fit’ layers that all deliver natural breathability, moisture control and, yes, temperature regulation, not at the touch of a button.

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.
