Woolpower is warm thanks to the terry knit of their base and mid layer insulation, their Ulfrotte material is 2/3 Merino wool and a 1/3 synthetic to make it long lasting.
Ulfrotte, unlike flat merion knits is warm when damp, I even use mine kayaking in winter.
Each seamstress markes the clothes that he or she sewed with their own nametag. Youll find the tag next to the washing instructions. Take a look inside your Woolpower garment. Is it for example Martha, Rokaia or Eleonor who made yours?
Woolpowers garments dont need to be washed so often as wool has naturally cleaning properties. Simply airing them out can be enough for them to feel fresh again. If you do want to wash them though, you can do so at 60 degrees.
The best way to stay warm is to follow the layering principle. You can combine Woolpowers clothes precisely as you want depending on what you plan to do. Are you going to move around a lot, or will you be standing still? How you dress will depend on the answer.
