Composition & Technology

Composition: 47% Thermowave Functional Polyester (Recycled), 42% Thermowave Merino Wool, 11% Polyamide.

Due to MerinoDry technology, you’re able to feel fresh, dry and warm for longer periods of time. We created a dual-layer, made from functional polyester inside and natural Merino wool outside, for faster moisture-wicking and additional warmth. Functional polyester quickly wicks away excess moisture, and Merino wool is known for ensuring warmth, as well as having natural antibacterial properties that protect from bad odours


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.

Recycled Polyester. The ideal sustainable choice, recycled fabrics utilize fewer resources in their production while retaining excellent fiber properties. For durable comfort with minimal bulk, recycled polyester provides exceptional moisture management, and moves freely with you, even through challenging activity.

Karin Rose (Los Angeles, US)
Great underlayer!

Bought this to use as an underlayer while skiing - lightweight, warm and breathable. I love it. My kids use theirs as an underlayer when playing soccer in the winter. They say they are barely notice they are wearing them. Thumbs up!!

Favorite Hiking Baselayer

I live in the Southeast and this is my go-to baselayer for hiking. It's perfect for our mild winters. I am constantly impressed by how well it regulates my temperature! I'm 5'3, 140lbs and typically wear a size 6. I opted for a size medium but probably could have sized down to a small for a snugger fit.

Great Shirt For Camping And Running

Great shirt with super nice fabric sits quite well on me. I took this one for camping as a sleepwear for summer because it's lightweight, soft, breatheable and has a hight collar, but now I think that I should take another one for running.


It’s the perfect gift for a man who works in unheated premises
