DETAILS

The Women'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.

Designed with Ultra Runners in mind we made it extra comfortable and extra durable. Made with lightweight 83% superfine Australian Merino Wool, 12% Nylon for durability and 5% Elastane for an easy four-way stretch and freedom of movement. Still Merino-rich, and perfect for adventure racing and what in Australia, we like to call ‘bush bashing’. The sporty fit is streamlined, but not ‘contact fit’ like the Altitude Base Layer Range.

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.

Designed with a body-skimming, sports fit. True to size.

Print to order. Exclusive 'Base 2 Summit' limited edition print.

Best Singlet that i have ever purchased

I purchased one a few years ago and it still going strong. So i decided to purchase four more, comfortable, cool and durable.

Love ioMerino

My wardrobe is full of ioMerino tees and long-sleeve tees. I love their fit and their feel, and wear them constantly.

Love my sheepish Tee

Bought the XS. It's a generous fit. Very comfy. Great quality, colour and style for indoor and outdoor. My preference is for longer short sleeves, especially outside. But very happy with this product

Comfy but. ..

Love the quality, colour and styling. I bought these for my partner and they are a little short in the leg length. He's not ridiculously tall and they sit above his ankles. Otherwise a good fit

So nice I bought them twice!

Super comfy and a go to item for all my pre and post adventures wardrobe in a duffel bag. So nice I had to buy them twice. Two pairs so I'm never without.
