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

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.

Fantastic shirt, worked really well in cool to cold conditions. Fit was pretty true I think.

Perfect function and design...

I own 3 of these tops now. 1 x for good, 1 x for home and 1 x well worn old job for camping/fishing. They are precious when new but better as they age and I care less about the nicks and holes. Perfect around home, brilliant out on the trails, up the river or at the cricket etc in the mid seasons. Always my go to option for comfort and transition warmth. I can wear this excellent top for a few days before a wash when out and about which I wouldn't do with a synthetic. Cheers R.

So comfy and warm but breathes so well

The fit is fantastic, and so comfortable to run in. Perfect for the cold dark morning starts, yet breathes so well once I get into my stride and heat up. Ultra satisfied with this next ioMerino product, you guys keep delivering the good stuff!

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.
