The MAC300 combines the protection of an immersion suit with the mobility and durability of a work suit. This integrated design reduces the weight and bulk of wearing multiple suits and features an innovative entry system that makes donning and doffing easier. The suit reduces heat stress while protecting against flame, immersion, and hypothermia hazards.

The anti-static, flame resistant Nomex® outer shell is strategically reinforced with leather in high-wear areas and can be easily detached from the Immersion and Thermal Modules to be worn separately as a flight suit. Using GORE-TEX® waterproof breathable fabric, the Immersion Module provides the protection of a dry suit and an adjustable neck seal using Mustang's patented Closed Comfort System (CCS™) worn loose to provide comfort out of the water and can quickly be drawn tight to keep the water out. The breathable thermal liner provides both insulation and emergency flotation and features aerated closed-cell foam quilted with a wicking fabric that pulls excess moisture away from the body.
