Fantastic Product8 December 2020These socks are the real deal, very comfortable, breathable and don't generate much perspiration. They also seem to hold up well. Many other bamboo socks don't live up to the marketing claims they purport because they mix bamboo with synthetic materials such as nylon. A real winner which I highly recommend to other prospective purchasers.
