Keep your head cool! Or no, nice and warm! Because if your head stays nice and warm, you will also get cold less quickly.
The snoods are also ideal. Just throw them over your head and no more hassle with loose pieces of scarf that get lost or can get caught somewhere.
And then nice warm hands! Ideal these mittens from Villervalla! Or those big ones from Smafolk for the more serious outdoor work ;-)
