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

The Keystone Tee can be worn on its own when you’re travelling or adventuring in warm to mild conditions and is perfect on its own during ‘in-between’ weather, whether you’re travelling, hiking or enjoying the outdoors. One top. Ready for many adventures.

All rounder

Purchased this as a general wear and athletic based Tee.
Fits the bill perfectly! and i'm currently wearing it most days under my Patagucci Nano for a great combo.
I'm 183cm and 83kg and grabbed the Large in this which is perfect fit. Noting, i grabbed the medium in the Altitude fitted base layer and it is great fit as well.

Base layer?

This T is more then a t, easily can be layered over or worn alone in warm weather, merino wool on your chest keeps you comfortable in the heat or cold.

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.
