We are rated excellent on Trustpilot
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.
