TROGE SURGI-FACE surgical face masks are made of soft, close-fitting non-woven fabric attached with 4 long non-tear tie strips. The integrated nose profile guarantees a close, secure fit to the wearer’s face. The asymmetric folds in the special 3-layer fabric provide very high breathability, preventing any unpleasant and annoying heat and moisture entrapment. The bacteria retention capacity is 99.9% - well above the required AORN standard. Also available with two elastic ear loops made of polyurethane.
