Everyone knows Merino is great at keeping you warm when it’s cold, but did you know our Keystone ‘Summerino' Tank is just as effective at keeping you cool when it’s warm?

The natural breathability and thermo-regulating properties of our MicroMerino® fabrics help keep you insulated against whatever Mother Nature can throw at you. The 100% Merino Tank is super fine, soft, lightweight, moisture wicking, odour-resistant, delivers UV protection from the sun and is a revolution in comfort all year round.

The Men's Keystone Merino Wool Running Tank features a sportier cut than a traditional, wide-strap tank top, and is perfect for those of us who love looking and feeling great. 

Designed to have a casual, relaxed fit. 

True to size. Model is 6'2" and wears size large.

Great singlet

Very fine quality wool. As good as NZ competition.

Thanks for the awesome review, Andrew! We work hard to meet expectations like yours, and we’re happy to hear we hit the mark for you.

Perfect everyday singlet

My husband has three of these Keystone running tanks and absolutely loves them. He wears them everyday and they have now replaced all his cotton singlets. The fabric is super soft and light and washes beautifully (no pilling). The singlets can be worn for days and never smell. The fit is great for exercise with the larger arm opening.

So glad to hear he's loving his new tanks! Thanks for the positive review Tash, we really appreciate it.

Just decent

Material is solid. Bought Navy and Thyme and they fit differently with the Thyme noticeably tighter. Also maybe it’s different in Australia but these tanks have the largest armholes I’ve ever seen in a tank. It’s a similar fit as if I cut the sleeves off a t shirt. Disappointed in the armhole size and different fit between colors so can’t recommend.

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.
