Improved Outer Tactical Vest

BETA Tags: IOTV, bodyarmor

The Army began fielding the Improved Outer Tactical Vest (IOTV) in the fourth quarter of 2007. The IOTV is a side-opening vest that provides a greater area of coverage than the Outer Tactical Vest (OTV) and weighs three pounds less.

The IOTV enhancements over the OTV include:

  • a reduction in weight of 3.8 to 3 lbs depending on size,
  • an internal waistband which moves more of the weight from the shoulders to the waist,
  • a mesh lining which aid ventilation,
  • side-opening which increases soft ballistic coverage and adjusts for better comfort,
  • a quick release handle by which Soldiers can instantly remove the vest in emergency situations,
  • integrated side plate carriers which decrease the vest's profile and allow better arm movement,
  • a lower back protector which extends the vest's coverage by 52 square inches,
  • a higher cut in the underarm area which eliminate the need to attach the axillary (underarm) protector to the deltoid axillary protector set,
  • integrated throat protector, and
  • increased number of available sizes for Soldiers with long torsos.
