  • Power button includes a battery indicator light that, when toggled on, quickly illuminates green, gold or red to indicate power level
  • Includes an UltrAspire rechargeable 18650 battery; features a USB Type-C charging port for a quick charge (includes a USB Type-C charging cable)
  • Race Fit™ conical shape, Fatigue Free™ buckles and limited-stretch elastic ensure a snug and stable fit that promotes a healthy and natural breathing pattern
  • Fatigue Free intuitive settings, large buttons and quick-release buckles allow easy operation for fatigued minds in extreme circumstances
  • Lightweight components and materials create an almost unnoticeable on-the-body feel without compromising durability
  • Proportional weight distribution and conical belt shape create a balanced load and a no-bounce ride
  • AutoCool™ heat-dispersing fins mounted in and around the light passively dissipate heat, keeping the light cool and efficient during heavy use
  • EnduraLight™ sturdy construction and aircraft-grade aluminum provide excellent durability and improved hot and cold tolerance while reducing overall weight
