For warmth, choose natural wool: alpaca, mohair, yak, and sheep's wool.
For winter sports, opt for fine and breathable merino wool.
For windy or milder weather, look for a cotton knit.
You can choose a colour that matches your coat to create an elegant tone-on-tone look or explore contrasts and have fun with a bright colour. Also, think about the colour of your other accessories (tuque, gloves) to ensure they all work together.
Scarves made of natural wool—like alpaca, merino, mohair, cashmere, yak, and sheep's wool—keep your neck the warmest during winter. Opt for tight-knit styles since loose knits allow more wind to go through.
Caring for silk is similar to caring for wool. Gently wash your scarf in warm water with a little mild detergent without scrubbing or twisting it, then rinse. Don't wring out the scarf. Instead, place it on a towel and roll it up to remove the excess water. To dry it, lay the scarf flat and let it air dry. Iron it inside out when it's still slightly damp and store it flat and away from light.
