Designed with ultra runners in mind the Women's Ultra Zip is as soft and comfortable as ever. Using our new core-spun fabric which combines all the natural benefits of our finest MicroMerino® fabrics with just enough nylon to create our most durable fabric yet, designed to withstand even the most demanding adventures.

Wear it on its own to stay cool in warm or mild weather, or as part of a layering system when the temperature drops.

Tag-free labels and flatlock stitching helps eliminate chafe and maximize comfort. The high collar and quarter zip add greater temperature regulation. Thumb loops keep your hands warm and stop your sleeves riding. Reflective trims have been added for extra safety in low light.

Designed with a body-skimming, sports / regular fit.

Love it

Perfect. I am very happy with the ultra zip and will be purchasing more. Love the look and feel of the top, the dazzling blue it a lovely colour. Thank you

Flattering and Super Comfortable

It is a more flattering fit than the Altitude as it is slightly loser around the tummy. I have several tops in the Ultra range and several in the Altitude range. I am a size smaller in the Ultra. If you prefer a more fitted look, then I suggest going down a size.
It's super comfy and feels a bit silky. I love the zip up as I can adjust the opening to regulate my temperature when I run. This top is a winter staple in my wardrobe, and has just enough room to fit snugly over an Altitude long sleeve zip-up top (as tested at Ultra-Trail Australia).

Thanks for your tried and tested review Sarah! If they can hold up in the Ultra Trail Australia ultra marathon, they can hold up to anything, right!?

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.
