ConclusionsConclusions• Lightweight, body-hugging protective

clothing can be constructed giving maximum protection to the wearer.

• Closure issue addressed for ease of donning and doffing the uniform.

• Better mobility due to breathing apparatus being located in an enclosed back pouch.

• Radio easily accessed on the jacket sleeve.
