The Men's Ultra Zip Base Layer top is as soft and comfortable as ever combining 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. Extra comfortable, extra durable and Merino-rich, perfect for adventure racing and what in Australia, we like to call ‘bush bashing’.

It is the ultimate in versatility and temperature regulation; roll the sleeves up, and pull the zip down when it’s mild and pull the sleeves down, zip up and thumb loops on when the temperature drops. Wear it on its own to stay cool in warm or mild weather, or as part of a layering system when the temperature drops.

This Base Layer is packed with extra performance features like tag-free labels and flatlock stitching helps eliminate chafe and maximize comfort. The high collar and ¾ zip add greater temperature regulation, while the thumb loops keep your hands warm and stop your sleeves riding. The reflective trims have been added for extra safety in low light.

Great tops

This is my second order of Ultra Zips. They are great - warm and comfortable, and even stay warm when the rain comes unexpectedly. Highly recommended.

Love it

Bought the Ultra Zip in Grey and I absolutely love it. This is my first IOMerino product and I’m really impressed by the quality. Feels soft, it’s super warm and fits really well. On the fit, I’m 5,11 (180cm) 75kg athletic build and while the medium fit was perfect across the shoulders, it would ride up if I put my hands up and was just a bit too tight to be comfortable for running and layering when climbing/mountaineering. I sized up to a large and it’s perfect.

Highly recommend this.

Awesome top!

I just recently bought this top to replace a similar style synthetic one. The difference is night and day! I was getting hot, sweaty and itchy under the synthetics on long hikes. The merino fabric feels so much nicer on my skin and breathes so well, the comfort levels have improved 10 fold! Also love the zip for chest cooling and the thumb loops to protect the backs of my hands from the sun. Well done IO 👏🏼

Cracking Product

My 5th or 6th IO top. Brilliant layering, easily packed for outdoor adventures and good enough for the pub. Can't fault ordering, sizing or delivery.
