3M Versaflo S-655 PAPR Hood Inner Collar Review — Extended Neck Coverage Accessory
Verdict: 4.2/5. The 3M Versaflo S-655 inner collar extends neck/shoulder coverage on S-series PAPR hoods without changing the APF 25 rating. A practical comfort and coverage upgrade for prolonged PAPR wear when workers flag neck-area air ingress or discomfort.
