Features & Benefits

Product Highlights
  • U1661 2 ply UD for improved flexibility for more comfortable armor solutions.
  • U1661 2 ply UD ballistic performance provides higher V50 and lower BFD in NIJ06 solutions.
  • U1661 2 ply UD maintains ballistic performance after environmental conditioning
  • U1661 2 ply UD patented resin formula allows for exceptional abrasion and solvent resistance.
Product Information
  • U1661 has been tested in accordance with NIJ06 tumbling protocol. Additional accelerated aging tests were conducted on U1661 using NIJ06 recommended conditions for the duration of twelve months.  This information does not relieve the user from the responsibility of testing the final ballistic construction.
