UPDATE – Nikken’s ThermoWear long underwear is currently unavailable and I do not know when or if it may return. I will update this page if/when that happens.
Leave me a comment at the bottom of this page if you would like me to notify you if the ThermoWear returns.
These comfortable, warming longjohns are not like other thermal long underwear because, thanks to special ceramic fibers, they gently warm you while not being so think and uncomfortable under your clothes.
The ceramic fibers in the material absorb ambient energy – your body heat, sunlight, etc. – and reflect it back to you as mild heat so that it heats you from the inside out. Excess heat is allowed to escape. I have used Nikken’s blankets with the same fibers since I started with Nikken years ago and the material works. I can’t remember the last time that I got cold at night, or woke up sweating either.
What You Need to Know About the Nikken Long Johns
- Special ceramic fibers keep you warm or cool
- Ultra-soft, luxurious fabric
- 3 sizes for women, 3 sizes for men
- Each set includes a top and a bottom
- Nikken ThermoWear is machine washable
- They are only available for a limited time
About that last point. For now, Nikken says that the new long johns are only available for a limited-time. I would love for them to become permanent because a lot of people have asked about them. The only way that will happen is if they sell well during this limited release.
