Liberty print face masks, one size fits all. Our facemasks have three layers, the outer is Egyptian cotton Liberty fabric, the inner filter is fine woven polyester to ensure quick dying and doesn't become soggy when worn, and a light cotton inner lining. The elastic has a gently knotted extension to allow you to adjust the fit for perfect comfort. This is probably the best fitting masks you will find. Being trained as a fashion and textile designer, and specialising in men's tailoring, you won't find a more comfortable fitting mask.
