Now you too can speak dog with this whimsical mask. Our masks are made from 100% cotton and are 3 layers thick. The outer layer is pre-washed flannel and the inner two layers are unbleached muslin. This design hugs your face without a need for metal on the nose bridge, making them washable and reusable. Machine wash warm and tumble dry low heat to avoid excess shrinkage. Adult and Children sizes available.
