This top is guaranteed to help keep you comfortable for longer come rain, hail, shine or all of the above. And as a three-time supplier of official UTA mandatory gear compliant thermals, you can be sure our gear is the real deal.

While merino is best known for keeping you warm when it's cold, its natural breathability and temperature-regulation also helps keep you comfortable when it's warm. So no matter what time of year, or what mother nature is dishing up, whether you're training or racing, you'll be good to go with io.

The Men's Long Sleeve Zip Merino top has all the features and benefits of the Crew, but offers even more versatility and temperature regulation: roll the sleeves up, and pull the zip down when it’s mild and you want some extra air, and pull the sleeves down, zip up and thumb loops on when the temperature drops.   


As with the rest of our Ultra range, it's soft, comfortable, and combines all the natural benefits of our finest MicroMerino® fabrics with just enough nylon to create our most durable fabric ever to withstand the most demanding adventures.

It's also breathable, moisture wicking, temperature regulating, odour-resistant, and designed specifically with Ultra Runners in mind.

This true high-performance garment is packed with extra performance features including tag-free labels and flatlock stitching to help eliminate chafe and maximize comfort. The thumb loops keep your hands warm and stop your sleeves riding, especially if you need to pull another layer or rain jacket on over the top, the reflective trims have been added for extra safety in low light, and the high collar and 3/4 zip make it even more versatile. 

Designed with a body-skimming, sports fit.

Genuine 83% premium merino-rich fabric.

True to size. 

Model wears size medium.

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.
