Janus Extra Warm

Janus Extra Warm is a thicker and warmer merino wool. It feels soft and good against the skin and insulates well. You can wear these woolen clothes directly on the body, or as a second layer on slightly cooler days. Merino wool has unique temperature-regulating properties developed by nature over thousands of years of evolution: it warms you when you're cold and cools you when you're too hot, and moisture evaporates easily. After knitting for more than 125 years, we've learned a thing or two about how to keep you comfortable and good, no matter what kind of trip you're on.
