I skied today (New Year’ Day, 2018) at Attitash-Bear Peak Ski Area in Bartlett, NH. The temperature was 0 with wind chill values at -26. You could really only stay out an hour at a time. I bought the Toucan to use as a helmet liner. It worked much better than I expected! It’s very light and thin, so it easily fit under my helmet, but it was amazingly warm! I went in not because my head was cold, but because my toes and thumbs were cold! The Toucan fits well and is very well made. And the merino wool is soft and comfortable, without the dreaded itchiness of other types of wool. If you buy one, you won’t be disappointed!
