Composition & Technology

Composition: 80% Merino wool and 20% polyamide (outside), 100% functional polyester (inside).

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.

Customer Reviews

Based on 4 reviews
Good Baselayer

Well fitting, comfortable baselayer. I use it for skiing and winter hikes. Nice texture and design.

Soft and Comfy

Soft and Comfy but wished for more wool on the inside. The inside is polyester which makes it soft but not as breathable as wool. Breathability helps keep you dry from your own sweat.

Good for high altitude gliding

Long searched for, finally found. Ideal for gliding at different altitudes.

Suitable for cold weather, soft fabric

Fits perfectly, breathable, soft, does not restrict movement. I recommend it to anyone working outdoors.
