The MSA Advantage 420 Half Mask Respirator with Twin Bayonet Connection in Small size represents a revolutionary approach to respiratory protection. This innovative half mask respirator combines exceptional comfort with sophisticated engineering, featuring a patent-pending one-piece UniBond over-mold face piece that delivers superior durability and stability without compromising user comfort. The device comes from the acclaimed Advantage 400 series and incorporates a unique harness assembly that makes donning and doffing effortless, even when wearing additional safety equipment such as helmets.
Designed with user versatility in mind, the MSA Advantage 420 features both drop-down and lock-down modes that allow wearers to remove the mask without affecting other protective equipment. The flat single loop harness prevents pressure points on the head when using head protection, while wide straps eliminate twisting and discomfort at the nape of the neck.

The chin cup includes a built-in drain hole for improved comfort during extended wear.

The one-piece MultiFlex nose cup is constructed from soft, smooth co-moulded silicone and rigid plastic, providing the perfect balance between comfort and structural integrity.
