Designed For All Season - Made from Standard_100 by OEKO-TEX certified fabric (often found within baby apparel), the mask provides a comfortable fit that conforms to the face for an ultra-soft wearing experience. Helps facilitate simple and effortless breathing throughout the day and never feels thick or heavy. | 2-Layers Of Filter - 2 layers of soft-worn fabric which facilitates protection during any outdoor excursion to the park, playground, or sports practice. A 2-layered filter helps prevent children from inhaling outside dust, dirt, and debris while out-and-about with friends and family. (Note: the fabric layers are made of polyester and elastane.) | 3D Design & Nose Wire - A 3D curved design with center stitching leaves sufficient space between the mouth and mask for easy breathing. Users will not “eat” the mask while talking. A unique nose bridge wire offers a snug and secure fit across the bridge of the nose which helps decrease “slipping”. | Fits & Adjustable - One size for all (kids 2-8 years of age). Designed as a universal and unisize fit. Just wrap the adjustable ear loops around both ears for a snug and secure feel. All masks conform comfortably around the facial area for a supportive and protective overall fit. | Reusable masks - The included 3 masks can be washed in warm water and used on daily basis.
