With the Blackhawk Ergonomic Duty Belt Harness, you'll be able to relieve the discomfort caused by the weight of an equipment-filled duty belt. Specifically selected and funded by the National Institute of Justice to address hip and back pain, this harness works to eliminate many of the issues often associated with external suspender systems. This harness is compatible with most concealment armor packages and accommodates duty belts up to 2. 25 inches wide. With no moving parts to fail and a broad fitting range for use with all body and body armor types, this harness shoulders some of the burden of your heavy duty belt. It can also be worn under a duty shirt with slight modifications.
