What is the difference between single curve and multi curve body armor plates?

Improved comfort and fit is a distinguishing factor between single and multi-curve designs. The more comfortable the armor is to wear, the more likely it is to be worn. Multi-curve models are designed to fit more ergonomically and anatomically when positioned against the human torso. This translates into an improved range of motion and longer wearability in the field. Hesco offers both single and multi-curve models to accommodate most any budget.
