The 3M™ DBI-SALA® ExoFit™ X300 Comfort Vest Safety Harness is designed for general industry applications requiring reliable fall protection and all-day comfort. Its vest-style construction helps distribute weight evenly across the upper body while providing a secure and supportive fit.

Engineered for efficiency and safety, the harness features an automatic stand-up aluminum dorsal D-ring for fast and reliable connections, along with an anti-sliding dorsal D-ring pad that helps maintain proper positioning. Integrated features such as the easy-link SRL adapter, low-profile suspension trauma straps, and auto-resetting lanyard keepers support efficient workflow and improved safety management. The integrated 3M™ Connected Safety ID (RFID) allows simplified equipment tracking, inspections, and inventory management.
