Composition & Technology

Composition: 100% merino wool.


Merino wool is like a personal air conditioning system for your body, so it will be able to maintain a stable temperature: keep the body cool when the weather is hot, and warm when it is cold. Environmentally friendly, merino comes from the best that nature has to offer – water, fresh air, sunlight and grass. It regrows annually, is up to 100% biodegradable and always performs at its best. Forget about unnecessary moisture, humidity and that itchy feeling because this is the softest and most breathable clothing you will ever find. Each garment at Thermowave has merino wool that is mulesing free. We are very proud of this decision, and we know that sheep welfare has improved given that more and more manufacturers follow this path. We have a saying that happy sheep don‘t itch and we stand by it.

100% legit

The way that this wool feels around my body feels so good… I like it… it’s not to thick it’s not to thin it’s just right!
Plus it also flatters my arms… it’s like the wool is hugging my body…
My name is Javier hernandez and I approve this WOOL!

Love this layer!

Comfortable right out of the box, great fit (I have long arms) and very warm. I've worn it on cold hikes and even to play volleyball on chilly nights and love it!


The ordered product meets the description and expectations. Very fast delivery.

Very good and skin-friendly for every situation

A very comfortable, soft and skin-friendly shirt, suitable for active wear or as underwear in very cold weather. I am happy.
