DETAILS

DETAILS

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.

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 Big Heart Adventure print.

Love the fit.

Fits so nicely, feels and looks really good :)

Perfect fit, great fabric

I like my running crop tops to be fine and this one fits perfectly. I am also really pleased to have merino directly next to my skin when I’m running and sweating. I’m so pleased with this!

not the right fit

I chose these over the Altitude style because of the blend - thought the 12% nylon would make for a longer lasting material. However, the fit is not right for me; they fit too low on the hips.
I've a 34inch waist and bought a Large.

Stripes Neck tube

Really great quality product, would have liked a bit larger size more like a snood. But looking forward to wearing 👍🏼

Loving this smart but comfortable T

This T-shirt is so comfortable for activity and is smart enough for the office, love it

Great undies

ioMerino trunks and boxers are just the best. People think that wool undies would be so uncomfortable, but nothing could be further from the truth. Silky smooth fine wool, not in the least pickly, stink resistant, so comfy. If marooned in the jungle for a week, these are the undies I would want to be wearing. And ioMerino is so helpful/cooperative if you find you have messed up your order. Highly recommend.
