I decided I needed a good, solid hat. Something cosy and warm and still a little stylish. After all, I'm sure I could wrap my head in Styrofoam, but even the sheep might take a second glance. The only problem is there are literally thousands of different hats on the market and dozens of different materials. I needed to find one that worked for me. But what is the best hiking hat for winter?

Wool is a well known material, as old as the hills, but there are also lots of things not everyone knows about woolly hats and you have been asking us lots of questions. We thought we would collate some of them and put the answers here.

The classic woolly hat goes by an assortment of local names. It turns out that in New Zealand, the United Kingdom and Australia, the term "beanie" is normally applied to a wool knit hat and it’s interchangeable with a Tuque, Touque and Toque in Canada and parts of the US. Touque, Toque and Tuque is in fact the same wool hat as a Beanie with three distinct spellings. And last but not least in the southern states of America, Toboggan is the name for a wool knitted hat that is worn during the colder months.
