Janus Extra Janus Extra is a range of underwear for cold weather. The garments in this range are therefore perfect for hard physical activity outdoors in the winter. Janus Extra has been tested and approved according to the EcoTex 100 standard, and is guaranteed to be free from substances which are hazardous for your health. The Janus Extra range is all in interlock or double-knit quality – this means that the garments are soft yet strong and have good elasticity.
