I love that these are hand made in Canada. They are quality items that look and feel good. There is even a bit of wire in the top to provide a better seal around the nose. I like that they're washable and reusable, from an environental point of view. But with several layers of cloth they can feel quite warm in hotter weather. This is perhaps less of an issue considering I'll be more likely to use the indoors (e.g. while shopping; air conditioned environments) than while outside.
