Breathability and moisture control

The proprietary 3M Cool Flow Valve is designed to ease breathing and help reduce heat and moisture buildup, contributing to a cooler, dryer experience during demanding tasks. The exhalation valve cover directs exhaled breath downward, which helps protect the valve area from debris and makes cleaning simpler.

• Cool Flow Valve can make breathing feel easier during work
• Moisture and heat buildup are minimized for drier, cooler wear
• Exhalation cover reduces fogging and debris exposure around the valve
