TORQ 61 concealable body armor maximizes American Body Armor's hybrid engineering with DSM's Dyneema SB61, a unidirectional (UD) composite that allows the energy of a bullet to be distributed among the fibers more efficiently than conventional woven fabrics. Engineered in a hybrid construction, TORQ 61 is thin and lightweight without compromising tenacity or strength. Dyneema SB61, a key component of TORQ 61, is not only 40 percent stronger than aramid fibers, but is weight-per-weight 15 times stronger than steel, while remaining soft and flexible. Also, Dyneema SB61 spreads back face deformation over a wider, shallower area, reducing the effect of blunt-trauma. Its advanced technology enables TORQ to provide additional resistance to moisture, UV light and chemicals.
