There are plenty of really great materials to choose from. If you check our ‘Materials’ section above, you will get an idea of some of the fabrics used in the construction of the products on our list. We love Merino Wool for a number of reasons. It’s breathable and can remove moisture better than other material types. It is a natural heating and cooling fabric, able to react to your body to see what it needs. Merino wool is also incredibly strong and resilient.
