A quick overview by Pale Horse Concepts of their TAC Inner Belt Mk4. This is a safety belt designed to be used as a traditional HRST belt. It can be worn as a standalone inner belt, or combined with an outer belt for added security. The tubular nylon material can be stored inside the running end's integrated belt loops. Available in nine-inch size increments, the Mk4 TAC inner belt is sized based on your typical pant size. To ensure proper fit, order the same size for both your inner and outer belts. The belt is worn through your belt loops like a riggers belt and is not a repel harness. The outer belt attaches to the inner using metal G-hooks and hook-and-loop closures.
