The 3M™ DBI-SALA® ExoFit™ X300 Comfort Vest Safety Harness is designed for general industry applications requiring reliable fall protection and worker comfort during work at height. Its vest-style design helps distribute weight evenly across the upper body, improving stability and comfort during extended use. Revolving torso buckles allow quick and efficient harness adjustments while locking the webbing in place to maintain a secure fit.

The harness includes an automatic stand-up aluminum dorsal D-ring for efficient fall arrest connections and an anti-sliding dorsal D-ring pad that helps maintain proper positioning. Additional integrated features such as the easy-link SRL adapter, suspension trauma straps, and auto-resetting lanyard keepers support safe and efficient workflows. The integrated 3M™ Connected Safety ID (RFID) enables simplified equipment tracking, inspection management, and asset documentation.
